10 t 1 hour run gas 2 t coal fired boiler investment costs: 2.8 yuan / Nm3 × 775Nm3 / h = 2170 dollars.
NOTE: the above-mentioned coal and gas prices, for reference, the case may be, depending on local circumstances!
We produce steam 2 t coal fired boiler is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback
The difference between Henan coal-fired 2 t coal fired boilers and gas boilers no matter what gas or coal can be used as fuel for boilers, however, named according to different types of boiler fuel use are not the same, so there is a gas boiler Henan and gas boiler that different types of boilers. So both types of boilers in addition to the fuel used in the combustion is not the same, between Henan coal-fired boilers and gas boilers, what difference does it make? 1, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while Henan gas boiler start and stop very convenient, fast warming intermittent operation, thereby reducing heat loss in this process. 2, after the treatment of different coal-fired combustion in the boiler will produce large amounts of ash after combustion, in order to maintain a good healthy environment need to transport ash to the professional field slag processing, however, gas-fired boiler using gas , there will be no remaining after combustion ash, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies. 3, the fuel is coal flue gas of coal-fired boilers used in different, when coal combustion will have a greater smoke caused serious pollution to the environment, however, high stability of the gas after combustion boiler did not smoke exhaust, because the basic gas on can be completely burned, toxic black smoke can reach zero ringelman level, SO2 content of which is very small, so there is no pollution to the environment. These three points above are some of the differences between Henan coal-fired boilers and gas boilers. By introducing the above we can understand the essential difference between the two boilers can understand, Henan gas boiler it is because of more environmentally friendly energy was gradually replace coal-fired boilers.
Boiler startup startup 2 t coal fired boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.Free Chat
