Operating costs of different fuel power plant packaged coal fired steam boiler comparison: Gas: Advantages: clean energy, high thermal efficiency and save costs. Disadvantages: Restricted gas on condition. Generating a cost of about 2.4 tons of steam million (calculated as the price of 3.0 yuan gas / side) fuel: advantages: no pollution, high efficiency, no fuel limitation. Disadvantages: higher operating costs. Produce one ton of steam costs about 594 yuan (fuel prices by 9.0 yuan / kg calculated) electrical heating: advantages: no pollution, no fuel limitation. Disadvantages: is a secondary energy, high operating costs to produce one ton of steam costs about 700 yuan (electricity prices by 1 yuan / kWh). Coal: advantages: low operating costs. Disadvantages: pollution, restrict the use of some areas, the cost of one ton of steam produced is about 150 yuan (coal prices by 1,000 yuan / ton). It works coal, gas steam boiler

A number of national influence energy consumption power plant packaged coal fired steam boiler coal to natural gas has been vigorous work, it should be transported steam boiler, very big eliminate the dust pollution, discharge of toxic gases and secondly nitric oxide, also got curb. Energy consumption is crucial mark measuring steam boiler, a good start and that is that work together to explore under the influence of a number of cases the energy consumption of steam boilers. Through the investigation of the persons concerned, the loss of heat from steam boilers bear the main two areas: combustion air-fuel ratio does not smoke emissions standards-related heat loss. Reduction of heat loss will install smoke emission in the flue gas heat recovery steam boiler terminal fitting, or should be transported more leading type condensation recovery boiler. Combustion air-fuel ratio standard fault summary: a conventional steam boiler burner ejector type, formed air-fuel ratio can not occur motorized adjustment. Some of the steam boiler with a mechanical blower burner, causing air-fuel ratio standard there are several aspects later: the main air-fuel ratio standard case encompass fall into two categories: air flow when exceeded, there will be an endless excess cold heat transfer, resulting in high energy cost of steam boilers, steam boilers reduced energy consumption; when the airflow is not enough, will have not exactly lit, the energy consumption caused by steam boiler weakened.
The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.
