Maintenance of gas boiler safety control three elements are: water gauge, pressure gauge and a safety valve. Wherein the valve is an important component, the effect when the boiler pressure exceeds a predetermined value, the exhaust steam can automatically prevent the pressure continues to rise, in order to ensure the safety of the boiler and turbine.
Electric boiler winter maintenance methods: cold winter approaching, north and south part of the city has gradually begun heating engineering. Boilers for its environmentally friendly, clean, no pollution, no noise, automatic and other effects electricity won the user favorite. So, how to maintain electric boiler should work to ensure the normal winter heating and other purposes?
Coal-fired steam boiler circulating pump hot water circulation pump to choose expansion tank: expansion tank is the role of regulator and safety storage expansion, expansion tank volume is proportional to the power of coal-fired steam boiler size, expansion tank usually go by the coal-fired the top of the steam boiler, in order to avoid falling into the dust tank, the tank cover should be set, but it must be open to atmosphere, the tank should be done inside and outside surface corrosion; circulating pump: pumps for circulating hot water circulating pump selection, to install circulating pump inlet inlet valve , the outlet non-return valve and the outlet valve; check: a check valve between the water supply valve and the backwater valve, toward its outlet to the water supply valve, a water circulation system to avoid water hammer occurs. Decontamination: decontamination role is to filter the debris back into the water, avoid the debris inlet opening and closing valve, affecting the normal operation of the valve opening and closing. The new heating system should be put into regular cleaning, decontamination dedicated cleaning very easy, do not set bypass conduit. Off valve: The principle is that when the circulating pump running, the pressure is transmitted to open and close the valve opening and closing valve is opened to form water circulation loop, circulating pump stops when the pressure disappears automatically shut-off valve, so that the user is at the top of the heating back water can not flow back into the expansion tank, while the user is in the water in the heating water supply pipe is high pump check valve (check valve) expansion tank does not return to the barrier, to keep the system full of water.
At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.
