Under the increasingly strict requirements of
urban environmental protection, new gas power plants are mainly built around
large cities; The original coal-fired power plant also changed the boiler
ignition system to natural gas, in order to substantially reduce pollution
emissions. Requirements of control valves used in gas pipes are also strict, zero
leakage is required, and it should be cut off automatically in case of failure,
as well as fireproof, flameproof, quick closing and continuous regulating. In 2005, after our company assisted Guohua(Beijing)
Power Plant to transform two boiler combustion systems, up to now, we have
completed the transformation of all eight boiler gas systems, including safely
cutting-off control valves and regulating cut-off control valves, which have
been in good use since operation.
