high efficiency industrial hot water boiler
First, preparatory work before the pressure test gas steam boiler 1, internal cleaning and inspection of the surface of the test portion. 2, to check whether or pipe clogging. 3, installed by a qualified legal department check the pressure gauge (not less than 2), after a year to conduct a check by the legal department. 4, close the valves on the gas-fired, the safety cover can be used to seal the valve seat, into the water from the inlet pipe at a locus (water temperature of 20 ~ 70 ℃), and the vent valve was opened evacuated vent valve was closed after the water to be filled . Ambient temperature should be above 5 ℃, or measures must antifreeze; and to prevent surface condensation boilers. 5, the pump inlet pressure test stand can be connected after a pump pressure. Second, a water pressure test gas steam boiler, gas steam boiler test pressure is 1.65MPa. 2, the water pressure should rise slowly, when the pressure rose to the working pressure should be suspended boost, check for leaks or anomalies, and then rose to the test pressure, maintained at this pressure for 20 minutes, then again down to work check the pressure, the pressure should remain unchanged during the inspection. Third, gas steam boiler pressure test security measures and precautions 1, is strictly prohibited flange bolts tightened when the pressure exceeds 0.3MPa. 2, the hydraulic pressure test, the scene should be specially marked to prevent accidental danger. 3 can not stand directly in front of the valve flange and the test weld. Fourth, the gas steam boiler hydrostatic test acceptance criteria 1, and no water mist on the walls of the pressure receiving element and the weld metal. 2, after the pressure test found no residual deformation.
The furnace product belongs to the basic type gas boiler, condensing gas boiler, a low nitrogen gas boiler are developed on the basis of production.
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam boiler fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.
The role of gas-fired boiler economizer, type and price: the boiler is a large energy-consuming equipment, gas boiler economizer is based on this born. To save energy, a high temperature flue gas discharged from the waste heat boiler reused, manufacturers will economizer mounted near the top or rear of the boiler flue, feedwater heating member. Mounted gas boiler economizer by lowering the flue gas temperature, can improve the efficiency of the boiler, so as to achieve the purpose of saving fuel.
