Chapter 343 Energy Use

The coking plant in the metallurgical department also produces gas, but the gas is basically used in metallurgy and metal processing, and there is no spare capacity to supply gas to other departments, and the distance is far away, so it is necessary to lay a well-sealed gas pipeline Carrying out long-distance gas transmission, manufacturing gas tanks to store gas... the traversers have not yet reached this industrial level.Therefore, the starting point of the industrial and agricultural gas stove designed by Wang Luobin is to be able to use gas locally.

Wang Luobin has a lot of materials on gas stoves, especially the materials on indigenous gas stoves, which can be said to be colorful and full of whimsy.But he did not trust the material.Indigenous gas stoves bloomed everywhere in the *** era, and the hype was blowing up, and there was no trace after the movement.Obviously, there are problems in terms of economy, safety and practicality.He lived in the countryside in the past, and he has experienced countless similar "technical promotions", such as biogas digesters, soil-based solar cookers... All of them disappeared or died of death due to various reasons.

It can be seen that the promotion of a new technology must take into account many factors, and the most important ones are practicality and economy.Neither of them is dispensable.

Therefore, in the selection and structural design of the gas generator, he discarded all the contents that were too "indigenous", and tried to "modernize" it within the scope of the traveler's industrial capacity to ensure its effective use. .

He chose a flat-suction circular furnace for the food processing plant, with a diameter of 1.5 meters and a height of 3.5 meters.Blower is used to blow air. This kind of furnace has a large hearth, uniform distribution of air and fuel, and high gasification intensity. It can gasify 60 kg of coal per hour.Required materials: refractory bricks, red bricks, cement and cast iron, all available from the industrial sector.The sealing method adopts water seal, which is simple and safe.The most difficult thing to make is nothing more than the reverse stop valve-this is a cast iron piece, and there is almost no difficulty.

After the gas is produced, it is firstly dedusted by a brick cyclone dust collector, and then the tar and dust are removed by washing with water, and the clean gas generated after cooling is used for the diesel engine.The sewage used for washing is recycled by the chemical industry because it contains a large amount of tar.

A high-power steam generator is also installed in the furnace, and the heat of the gasifier is used to burn steam when the fuel is gasified, which also solves part of the demand for steam in food processing plants.

In order to facilitate ventilation and avoid carbon monoxide poisoning, the gas stove is built under an open shed.The gas generator, blower, and diesel engine are integrated into a power workshop. The gas-driven diesel engine drives the belt to drive the horizontal shaft for transmission. Various machinery and equipment can be driven by connecting the belt on the flywheel to the horizontal shaft.This Changchai 22-horsepower engine is enough to meet the entire power demand of the food processing plant-including the demand for the blower to keep the gas furnace running.

The furnace was successfully ignited once after it was built, and the fuel used was coal from Leizhou.After the Leizhou Sugar Company won the sugar war, they made persistent efforts and took advantage of the great opportunity that Zhu Sanye's family was killed, and directly annexed Zhu Sanye's boat company.In addition to transporting sugar to Guangzhou and Lingao, more than a dozen large ships also transported coal—all of which Chang Shide sent people from the local area and nearby Gaozhou and Lianzhou to purchase them.This kind of coal is relatively inferior and suitable for gasification.

Another advantage of the gas stove is that the requirements for the fireman are not high, and there is no need to talk about any technology, as long as the work is done strictly in accordance with the regulations.The work of feeding is not heavy, and it does not need to add coal all the time like burning a boiler.Wu Nanhai chose an old man in his fifties from the semi-labor force of Bairen Commune to take care of this matter. Although he looked very old, he still had strength, sharp eyes and ears, and was not confused.

When the gas stove was ignited, Wang Luobin personally came to start the diesel engine with the hand lever. After a few crackles, the diesel engine started to "chug" and it felt the same as when using diesel.

Wang Luobin used the gas stove in the food processing factory as a demonstration sample of the gas stove

Huang Dashan appreciates the gas furnace project very much - the gas has a high calorific value and stable heat generation, which is very beneficial to temperature control. For fermentation and enzymatic decomposition, the temperature requirements are quite strict.

The gas furnace in the food processing factory has greatly alleviated the consumption of biogas produced on the farm. Originally, this was the largest consumer of biogas on the farm.The biogas production of biogas digesters is very unstable. Wu Nanhai's biggest problem is that he has built a lot of biogas digesters, but no matter how good the design of the ponds is and how big the capacity is, there will always be a problem of reduced gas supply from time to time. Suddenly stopped.Fuel has to be urgently called to replenish.

Wang Luobin personally watched the stove for a long time beside the stove, observed the burning situation, and after feeling that everything was normal, he then took care of Mo Xiaoan: "In this shed and several nearby workshops, bird cages are hung up to raise a few birds."

"What do you do with birds?"

"Be an alarm, so as not to be poisoned by carbon monoxide." Birds have a much lower tolerance to carbon monoxide than humans and can warn of carbon monoxide leaks.

"No need. The gas leak smells so strong, it's impossible not to smell it..."

Wang Luobin glanced at the Minister of Light Industry: "Carbon monoxide is colorless and odorless. The smell is added."

"Understood, I understand." Mo Xiao'an Dahan—this is not a shame on the spot, "I will arrange it now."

Wang Luobin went around the food factory again - he now has an important task to estimate the energy consumption of the traveler, so as to make overall arrangements for the various prime movers and energy currently used, so as to improve their utilization efficiency.

The prime movers currently used by the Travel Group are electric motors, which rely on two power stations and sporadic wind generators for power supply.

The electric energy is clean and convenient to use, and the electric motor works stably, so it is naturally the best choice for the prime mover.However, in an internal assessment by the Industrial Energy Commission, it is considered that electric motors and various equipment related to electricity, including generators, transformers, transformers, cables... self-production is very difficult-this difficulty is mainly reflected in materials.In particular, the magnetic steel sheets used in electric motors are far from being manufactured by ordinary local methods.In terms of the industrial capabilities of the Crossing Group, it is not difficult to manufacture equipment. The difficulty lies in the fact that the raw materials can only be used from the reserves brought, and there is no replenishment when they are used up.Considering the need to replenish damage and repair equipment, these materials and parts must have a certain amount of inventory.Before overcoming these problems, electricity is obviously not the main direction of development.

Beyond the electric motor is the steam engine.This kind of machine has been gradually popularized in various places since the machine factory put into mass production the 50-horsepower Mozi II. The steam engine has the worst efficiency because of its low technical content.Boilers can be fired with a wide variety of fuels.It is the main source of power for the traverser in the near stage.

As for diesel engines, gasoline engines and the like, they rely on stored petroleum fuels, and now they will have a wide application prospect after they are gradually "gasified".Although the output power of the internal combustion engines they have is relatively small, they have the advantages of small size, light weight, and easy movement, which are much more convenient to use than the heavy steam engine + boiler power combination.The gas generator can be large or small, with flexible configuration, and the demand for fuel is not high.

Promoting gas generators is only one part of the plan.Wang Luobin also plans to improve the efficiency of fuel use through deep processing of fuel and transformation of combustion devices.

There are many kinds of fuel used in the journey. Apart from the fuel oil and the biogas produced by the biogas digester, the most important fuel is coal. It is indispensable in everything from the boiler of the steam engine to the fire in the cafeteria.Followed by various wood scraps, sawdust, straw and the like.The calorific value of various fuels is different, and the use is also very extensive.Wang Luobin proposed in the plan to change the random and non-standard practice of distributing fuel in the past, and instead set up a fuel factory, which will pre-process all kinds of fuel except for biogas, and then be used by various departments.

For the time being, a simple coal processing workshop will be set up in this fuel plant, and at the same time, the original wood distillation kiln will be received.

The coal processing workshop is responsible for washing the coal transported from other places.The coals shipped from Hongji and Guangdong are all mined by local methods, and a lot of impurities are mixed in them, and the quality of the coals is also different. The coals with small internal ash and large internal ash are mixed together, indiscriminately. Throwing it into the boiler for combustion will cause a lot of waste.

The impurities in the raw coal are removed by coal washing, and then the high-quality coal and the low-quality coal are simply classified.Remove coal gangue.Pulverizing coal according to its purpose can greatly improve the efficiency of coal use.

Wood fuel, except for sawdust and materials that cannot be carbonized, is no longer directly burned, but enters the carbonization kiln to be carbonized into charcoal, which improves combustion efficiency, reduces pollution, and recovers wood tar at the same time.The waste heat of the dry distillation kiln is used to produce steam by the evaporator, which is supplied to Bopu's factory.

In addition to coking coal, fuel coal and charcoal are uniformly converted into standard coal units for use by various departments in order to accurately calculate the fuel usage of each department.

The fuels of rice straw and chaff are controlled and used by the Council of Agriculture.For chaff, Wang Luobin does not recommend not using it as fuel for the time being—this stuff contains a lot of silicon dioxide, which is very polluting when burned.When the fuel requires special devices to be used effectively.

For the many stoves that are currently available in canteens, factories, and dormitories, except biogas stoves, Wang Luobin decided to conduct a comprehensive investigation and registration, unify the stove types, remove simple stoves that do not use fuel and heat energy well, and at the same time force the promotion of the use of briquettes .The manufacturing technology of honeycomb coal is simple. Use the coal powder at the bottom of the fuel plant to screen the coal and grind it once, mix it with loess in proportion, and use a simple hand-operated briquette machine to make it.Two or three workers can make thousands of them a day, which is enough for these furnaces.
