Big Capicity Coal Fired Steam Boiler

Big Capicity Coal Fired Steam Boiler

Operating costs of different fuel big capicity 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

Effect of boiler fine coal combustion boiler operating principle is to use thermal energy or heat in industrial post fuel released by combustion is transferred to the water in the container, the temperature or pressure of the water reaches a certain desired steam heating equipment. Many people will feel that coal-fired boiler more detailed the better, but is it really? From a combustion point of view, the finer coal particles more easily form a good mixing with the air, the more complete the combustion. But the coal particles too small, for boilers, milling power consumption will be greatly increased. Industrial boiler, the coal into the furnace too small, there will be the following questions: 1, coal leakage losses, etc. from grate gap increased. 2, boiler grate to be at full speed, power consumption increases. 3, fly ash, fuel loss increases. 4, a coal burning ember i.e., unstable combustion, furnace volume heat load difficult to sustain stable. So the boiler when using fine particles of coal, coal is subject to how much water, raw coal water, play groups and then into the furnace. If the burning coal of 8 to 12h before the water, so that the penetration of moisture into the interior of the coal particles is better. Water vapor produced is moistened triatomic gases, flue gas can strengthen radiation, facilitate ignition, exhaust and reduce heat loss

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.

Cooperation with the fast boiler really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
