coal assembly pipe steam boiler china

Pressure coal assembly pipe steam boiler china shutdown fire you do not know the techniques and precautions steam boiler refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, It is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. Fire pressure steam boiler shutdown is interrupted by slowly burning until the load drops to zero until a planned shutdown. Specific steps are as follows: 1, to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. 2, the distance to the thick seam slag is about 1 mm grate stop rotation of the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the gas will move back some distance. 3, the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, to resume operation .

Gas-fired coal assembly pipe steam boiler china applications include gas steam boiler steam boiler and hot water boiler two categories, under the policy from coal to gas, the use of gas steam boiler is also increasingly widespread up. Regional gas boiler is also engaged in the implementation of replacement or renovation project. Then come to you simply steam boiler applications have what? Steam boiler applications can be roughly divided into three categories, residential, commercial and industrial, civil and generally refers to the domestic gas boiler our lives with so-called boiler, primarily for home heating and bath with hot water , which is characterized by simple structure, convenient operation, long life, is the choice of most families choose; commercial, then generally refers to the star hotel, hospital school district heating mechanism, the general will choose to steam bath or gas boiler boiler for hot water supply of the main ways. Required in this area to select a gas boiler, characterized in that the gas or gas compared in terms of biomass fuel, no dust combustion, emissions in the flue gas can also control the amount of nitrogen emissions. Gas-fired steam boiler combustion more fully in value, mostly in the commercial is also a good choice; the last is the industrial furnace, industrial furnace is characteristic of large tonnage, high fuel demand, in general, the company received the heat a gas pipeline to gas as fuel, then the biggest advantage is that no storage, reducing transportation and storage costs of fuel, generally used for thermal power generation or industrial heating and heating company needs large industrial enterprises. These are the three main areas of use on gas-fired boiler to introduce today, hoping to help you have a better understanding of steam or hot water boiler, also hope that we can continue to focus on.

"APH T6" boiler circuit to meet the various needs, select single or series and parallel, with the use depending on the circumstances. Premix combustion technology with technology and wings, by fine adjustment control, to promote efficient mixing of gas and air, the combustion more fully, more efficient, suppressing the generation of NOx from the source. Beijing new boiler The boiler NOx emissions less than 18mg / m3, well below the most stringent in the history called "boiler air pollutant emission standards" under the implementation of emission limits 30mg / m3 of.

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
