pengalaman boiler batubara chain grate dan fluidize bed

Our environmental management efforts continue to increase, located in Wuhai City of Inner Mongolia is also actively respond to national policies, by removing, shutting down non-compliance of the measures within the jurisdiction of coal-fired pengalaman boiler batubara chain grate dan fluidize beds, etc., to improve air quality within the city.

Recently, a reporter to follow the staff Haibo Bay Area environmental monitoring brigade, examined the case of shutting down coal-fired boilers in rural areas. Trinidad town in Wuhai unity Village, coal-fired boiler is the main source of heat in the village residents, schools, hospitals in the town and airport, but because they do not meet environmental requirements, the boiler has been officially shut down at the end of 2018. Haibo Bay Area Environmental Protection Agency environmental monitoring battalion to us to: "Removing the boiler is 20 tons of steam coal-fired boilers, each heating season about to burn more than 3,000 tons of coal in accordance with the municipal government requirements. within the deadline 20 tons of steam boilers to be all removed, replaced with clean energy. since November 2018, this block of sea area has access to a central heating all children. "

So far in 2013, Wuhai City in strict accordance with regulatory requirements grid, earnestly implement the responsibility of inspectors on-site supervision, and has eliminated 20 tons of steam coal-fired boilers for heating and tea bath furnace 791 units, of which 2018 out of 58 units. Meanwhile, municipal and district environmental protection departments at all levels to increase on-site law enforcement and ensure that the boiler is no longer out of the resurgence. Up to now, it has no built-up area of ​​Wuhai City and 35 tons of steam coal-fired boilers to achieve a stable discharge standards.

A few disadvantages of wood poles and timber fired pengalaman boiler batubara chain grate dan fluidize beds are common to each of them in varying degrees are: Low residence time of material in the combustion zone (except stokers) requires high combustion temperatures to assure adequate combustion efficiency without excessive unburned carbon losses. High temperatures, usually more than 980°C, contribute to the formation of nitrogen oxides, which are environmentally objectionable. High combustion temperatures also dictate the use of post-combustion treatment scrubbers for removal of sulphur dioxide (SO2). When the combustion temperature is maintained between 815°C and 870°C, SO2 removal can be accomplished by injecting limestone (CaCO3) directly into the furnace.

The main results are as follows: (1) the pengalaman boiler batubara chain grate dan fluidize bed of heating system of pressurized hot water boiler is pressure-bearing equipment, which has the danger of explosion. The boiler in the heating system of atmospheric hot water boiler does not bear pressure and is always connected with the atmosphere, so the boiler will not explode under any circumstances, and the safety performance is good. (2) the pressurized hot water boiler is full of water, and there is no water level control problem. There is water level control problem in atmospheric pressure hot water boiler. (3) pressure gauges, safety valves and thermometers must be installed for pressurized hot water boilers, because the boiler is always in a full water state, so there is no water level gauge, and there is no water level gauge at the top of the boiler. (3) A pressurized hot water boiler must be equipped with a pressure gauge, a safety valve and a thermometer, because the boiler is always in a full water state. But the atmospheric hot water boiler is only There are water level gauges and thermometers, because the boiler is connected to the atmosphere, the pressure in the boiler is always atmospheric pressure, and there is no danger of explosion, so there is no need to install a safety valve or a pressure gauge. (4) circulating pumps in the heating system of a pressurized hot water boiler. Is the pumping system to return water to the boiler, the general selection of clean water pump. It should not only overcome the circulation resistance of the system, but also maintain a certain pressure of the boiler to ensure that the boiler water does not vaporize at high temperature. The circulating water pump of the heating system of the atmospheric hot water boiler is pumped from the boiler, the pump is the hot water pump, its function is to overcome the system resistance, mainly to overcome the resistance of the return water regulating valve. (5) pressurized hot water boiler Can supply both low-temperature water and high-temperature water. But atmospheric pressure hot water boiler can only supply low temperature water less than 100 ℃.

WNS series diesel oil fired steam pengalaman boiler batubara chain grate dan fluidize bed has importer burner in designs. It can realize 92% thermal transferring efficiency in boiler service time. Packaged diesel oil fired boiler technology requires minimal maintenance or attention during normal operations. Automated monitoring and control systems run all aspects of this packaged boiler, including feed, load reduction, and tube cleaning, and continuously adapt as system conditions change. Operational stability enables smallscale operations with small maintenance support teams, thus reducing labor costs. Automatic operation system is convenient to boiler operator.
