銆€銆€Boilers, steam turbines and generators are the three core equipment of the power plant. The boiler burns various fuels to heat the water to generate superheated steam, which converts the chemical energy of the fuel into heat. The superheated steam pushes the steam turbine to work, and converts the thermal energy into mechanical energy. Then the steam turbine drives the generator to rotate, converting the mechanical energy into electrical energy. This is the basic principle of thermal power generation. Knowing this, together with relevant physics knowledge such as the law of conservation of energy, can gain a deeper understanding of the relationship between the capacity of the boiler and the amount of power generated by the boiler.
How Jinju small steam boiler to buy a particularly large number of companies in fact the number of small steam boiler needs a lot, so this kind of small steam boiler, also known as the steam engine, the water temperature of the combustion engine reaches 100 degrees Celsius, will quickly form a saturated steam, thus achieving the production needs of buyers. This is we often want to know the small steam boiler. So how about we buy steam boilers, in fact, we generally can be to buy from fuel steam boiler or own superiority, some consumers need to solve the power output on their own, we can buy the electrical energy of the steam boiler can greatly reducing the cost. If the steam boiler extraordinarily large size, fuel gas line did not penetrating, optional biofuel steam boiler, can weaken fuel costs, the production of biofuels by himself, can quickly achieve combustion of the fuel. If the value of the saturated steam demand exceptionally small, optional she said single phase steam generator, with a small cost to do a big demand!
Jiamusi City, Heilongjiang Province Tangyuan county government to further implement the "Heilongjiang Provincial People's Government of Heilongjiang Province on the issuance of three-year action plan to win the notice of blue sky Wars," the actual situation, carry out a comprehensive rectification for small coal-fired boilers, as follows .
First, the objectives
By the end of 2019 out of the region to build 26 units per hour and 10 tons of steam coal-fired boilers and furnaces tea, operating a stove, food equipment and other coal-fired kiln drying facilities. Out of which 14 coal-fired heating boilers Small units, service three coal-fired boilers, industrial production of small coal-fired boilers nine. By the end of 2020, the region will build small coal-fired boilers cleared number, and completed more than 10 tons of steam per hour of coal-fired small boilers governance standards.
Second, the specific content of execution
1, source control. County-level cities built in the region 35 tons of steam per hour ban on new coal-fired boilers, the rest of 10 tons of steam per hour ban on new coal-fired boilers and below.
2, find out the base. Focus on carefully checking the area of coal-fired boilers case, before the end of May, the completion of the area and the development of coal-fired boilers ledger built-up area, and clearly out of all kinds of coal-fired boilers responsible departments and completion time.
3, held a mobilization meeting. 10 tons of steam per hour, organization and small coal-fired boiler unit, responsible departments held a meeting to clear out of time limits, and invite gas companies, boiler manufacturers, heating companies and small boiler unit for docking, to help provide alternative solutions Program.
4, announced the phase-out plan. Through government websites, issued to small coal-fired boiler unit a variety of ways such as notification, publish small coal-fired boilers out of the list, time frame for completion and telephone hotlines.
5, to carry out law enforcement inspection. Organization of joint law enforcement inspection, supervision of small coal-fired boiler unit to carry out the planned phase-out time frame. Carried out errant time, press the "Heilongjiang Province Air Pollution Prevention Act," the imposition of penalties.
Xiao Bian tell you about the boiler combustion optimization control of those things: the boiler is an energy conversion device, in other aspects of power plant systems have been developed under perfect circumstances, boiler combustion system is a major part of energy-efficient coal-fired power stations and savings. Now, with the burner technology is improving daily, it has been able to adapt to all kinds of fuel combustion conditions and load, but the new requirements of energy saving power companies makes burning power plant boiler combustion stability not only meet, but also to meet the combustion process efficiency and reduce pollutants requirements emissions. It is necessary to further optimize the combustion process and operation. Today, we learn more about it. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. So, generally we use combustion expert system to monitor the implementation process, maintaining the boiler combustion efficiency and energy saving. Automatic water boilers, reaching full of water replenishment stops automatically, not manned, save time, save time, effort, labor. Increasingly comprehensive boiler combustion control means and the cumulative operating experience, providing adequate conditions for the implementation of expert systems. By burning power plant boiler combustion expert system of real-time status monitoring, by the mathematical model and expert system established by the corresponding combustion, can effectively adjust the boiler combustion, state correction due to various factors to the combustion process caused by deviation, to achieve optimal control of combustion. Structure designed according to the boiler pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic aspect. When using the boiler operation, hold down the control key forced to manually start and stop the boiler with water, the water level reaches very low safety level, the boiler automatically stops pay, the microcomputer controller after setting the boiler, the boiler began to work fully automatic, automatic replenishment, automatic heating, when the set temperature is reached, the boiler into the automatic insulation state. The coal boiler according to data analysis, secondary air damper temperature, and the load carried by the boiler combustion conditions, the coal and air flow control system to protect combustion boiler at its best, achieve fuel economy, reduce emissions of pollutants. The experience of the steel and building materials industries, the expert system can be achieved using combustion burn energy saving 2% -5%. You know what Btu boiler is not it?
