Boiler Diesel System

Test operation steps of gas-fired steam boiler diesel system

Gas-fired steam boiler trial operation is an important part of comprehensively testing the quality of the design, manufacture, installation, commissioning and production preparation of the main engine and its supporting equipment. It is an important procedure to ensure the safe, reliable and economic operation of the boiler in the future.

Inter-regional Pingdingshan Coal Industry Group Co., Ltd. by the Pingdingshan Shenma Group and two Chinese top 500 enterprises founded by restructuring, cross-industry, cross-ownership and transnational business of large state-owned energy and chemical group, under the People's Government of Henan Province , is the most complete variety of coking coal, thermal coal production base, has Asia's largest chemical production base in nylon. Carefully selected and comparison, fast boiler diesel system Pingmei cooperation with party has chosen to provide a 2 tons of steam electric steam boiler (WDR2.0-1.25-II) by a fast side.

Preparation before circulating hot water boiler diesel system blowdown and description of the kind: the hot water boiler, in addition to the existing outside of the front, we should be learning what knowledge, understanding and knowledge? Why raise this issue, its purpose is very simple, in order to elicit the article content to give you some further knowledge and understanding, in this kind of boiler hot water boiler, and at the same time, also can increase their professional in this area Knowledge. 1. The operation of the hot water boiler then its need for workers operating certificate? For special operations personnel it? Hot water boiler operation, then, is that workers need to have the operation license. And it's also a must. In addition, we should also know is that hot water boiler capacity and different parameters in the operating permit, there is a corresponding different levels of operating permits, therefore, not be mixed. While special operations personnel, can be very sure, it is a must have operating permits, otherwise, can not start to work.

First, preparatory work before the pressure test gas steam boiler diesel system 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.
