The working principle of steam boiler steam boiler with boiling water almost equivalent to pot kettle, oven stove equivalent. Boilers and boiler furnaces is divided into two parts, the pot is filled with water to a metal container, partially combusted fuel furnace, the heat absorption of the water inside the pot furnace fuel combustion converted to steam. Popular terms, the steam boiler is to absorb combustion heat of the fuel into the water some parameters (such as pressure, temperature, etc.) of the steam device. For example, everyone knows to pulverized coal, for example. 1. The operation principle (an example in pulverized coal fired boilers) in heat pulverized coal combustion furnace, radiative heat transfer is first absorbed by the water wall, the Wall Boiling water, a large amount of steam into the drum for steam separator (DC furnace excluded), the separated saturated steam enters the superheater, and continues to absorb the furnace top horizontal flue by means of radiation, convection, heat of the flue gas flue of the tail, and the superheated steam to reach the required operating temperature. Power generation boilers are generally provided with a reheater, it is used to heat the steam through the high pressure cylinders acting reheater go out of the reheat steam, the low pressure cylinder to continue to generate power. 2. Pulverized work, the center position of the flame will impact the amount of evaporation, generally, the lower the evaporation flame kernel, the flame kernel high evaporation amount is small; also affects the position of the center of the flame superheated steam or reheat steam temperature, generally lower the center of the flame in particular superheated steam reheat steam temperature to be low, otherwise higher. 3. The arrangement of the burner, pulverized coal fired boiler on, the current embodiment there are opposed wall, more Tangentially combustion, combustion bis Tangentially the like, each have their own characteristics, can not be applied because the same furnace at the same time several above-mentioned arrangement, the steam still can not directly affect the conclusion.

Classification of Oil-fired BoilerCompared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Fuel-fired boilers are heated by burners, and fuel-fired atomization effects Good fuel combustion, smokestack can not see black smoke, so fuel-fired boiler green, efficient and energy-saving. Oil-fired boilers include oil-fired water boilers, oil-fired non-pressure hot water boilerss, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil.

Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.
