China Dunhuang International Hotel relevant responsible person said, party fast or aftermarket both in pre-sales, remained consistent patient service, we have solved many difficult problems, with fast boiler for carpentry equipment, we are assured. --customer feedback

Second, grasp the "coal to gas," the key link.

1, removal of the original coal-fired boiler slag machine, coal hopper, coal equipment, chain grate, gearbox and so on.

2, by calculating the heat transfer in the furnace, the furnace geometry is determined, the center position of the furnace flame. Re-casting furnace, the furnace using the refractory castable

You must know the boiler for carpentry equipment energy problems (induced draft fan power consumption rate, steam consumption) draft fan causes problems 1.1 boiler flue dust and fouling, in particular air preheater fouling, resulting in increased resistance to smoke duct . 1.2 boiler flue, tail heating surface and dust leakage. 1.3 Leakage Rate large air preheater. 1.4 furnace excess air coefficient is too large. 1.5 unit load changes, run the adjustment is not timely, resulting in furnace pressure is too large. 1.6 unit load or low frequent starts and stops. 1.7 coal into the furnace worse, from the design value. 1.8 low efficiency filter. 1.9 draft fan blade badly worn, low operating efficiency. 1.10 fan outlet flue gas desulfurization big resistance. 1.11 soda boiler pipes for leaks. 2, 2.1 to 2.1.1 operational measures to solve the problem of the strict implementation of soot blowing system to prevent the heated area ash, blocking ash, flue gas system to reduce resistance. 2.1.2 holding the induced draft fan, the flue gas separator baffles and dampers in the fully open position. 2.1.3 The experiment showed combustion boiler, proper control of excess air in the furnace. 2.1.4 adjustment chamber negative pressure, air leakage reduction furnace and the flue. 2.2 routine maintenance and testing 2.2.1 induced draft fan performance test to determine the optimum operating point and efficient workspace. 2.2.2 boiler, air preheater, a flue, ESP and other system leakage inspection, process. 2.2.3 timely check processing chassis, shaft seal leakage. 2.3C / D repair, eliminating defects 2.3.1 down strict accordance with movement clearance adjusting fan. 2.3.2 induced draft fan blade defect action elimination hand vane opening adjustment. 2.3.3 Importers and induced draft fan baffle opening check. 2.3.4 duct tightness check process. 2.3.5 wave plate replacement air preheater, rinsed sector plate gap adjustment. 2.3.6 eliminate dust defects and improve collection efficiency. 2.3.7 clean flue gas desulfurization system, flue resistance is reduced. 2.3.8 eliminate soda boiler pipe leakage defects. 2.4A / B repair and transformation 2.4.1 Check and repair the fan blades, replace seriously damaged blades if necessary. 2.4.2 for energy saving fan efficiency below 75%. 2.4.3 The fan motor frequency transformation. 2.4.4 of the precipitator, if necessary, transform and improve collection efficiency.

3, coal combustion boiler for carpentry equipment technology

This technique is performed by coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of the suspension increases combustion energy can be obtained a certain rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed.
