As one of Beijing's air pollution emission standards of the most demanding urban, environmental control is very strict. Beijing primary school campus Emerald City as one of the cradles of socialist culture successor, in terms of the quality of students' learning environment is put emphasis on one hundred percent. October 2017, Beijing primary school campus Emerald City with my company, signed a two Thalia T6 series vacuum hot water automatic condensing boiler supplier for winter heating use.

Gas-fired steam automatic condensing boiler supplier safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.
What is the difference between the gas automatic condensing boiler supplier and coal-fired boiler? Whether gas or coal can be used as fuel for boilers, however, named according to the type of fuel used for different boilers are not the same, so there is such a different type of gas boilers and gas boilers. So both types of boilers in addition to the fuel used in the combustion is not the same, between the coal-fired boilers and gas boilers, what difference does it make? 1, fuel is coal flue gas of coal-fired boilers used in different, when coal combustion will have a greater smoke caused serious pollution to the environment, however, high stability of the gas after combustion boiler did not smoke exhaust, because the basic gas on can be completely burned, toxic black smoke can reach zero ringelman level, SO2 content of which is very small, so there is no pollution to the environment. 2, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while the gas boiler is very easy to start and stop, fast heating intermittent operation, thereby reducing heat loss in this process. 3, different treatment after burning coal combustion in the boiler will produce large amounts of ash, in order to maintain a good healthy environment need to transport ash to the professional field slag processing, however, gas-fired boiler using gas , there will be no remaining after combustion ash, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies. This is more than some of the differences between the three coal-fired boilers and gas boilers. By introducing the above we can understand the essential difference between the two boilers can understand, it is because of gas boilers more environmentally friendly energy was gradually replace coal-fired boilers. However, if companies need to use this boiler, in order to advance understanding of the security needs of gas-fired boilers which have quality assurance.
