steam boiler high quality in korea
By adopting international condensing boiler technology advanced, so that the boiler is obtained using a higher value, the boiler is called generation. According to user needs, can output high-quality steam or hot water, is widely used in heating and hot places. Under normal operating environment of the boiler, can reach more than 108% thermal efficiency, the use of heat to the extreme. Why, then, such as hospitals, hotels, shopping malls, schools and other places like using a condensing boiler it?
"Can shipped on time, not only the ability to schedule Tianjin coal-fired boiler project and the Tianjin Municipal People spend time heating, but also on our fast boiler brand image, so we have to work overtime quality and quantity the coal-fired boiler complete product supply mission. "fast square to official said. Facing short construction period, heavy task difficult, we rationalize production processes, all front-line staff hard working, eventually will be shipped on time to the boiler Tianjin, and running. After the boiler in place, Tianjin coal-fired boiler project also completed the basic preparation, coal-fired boilers, Tianjin is also a blue sky will gradually improve and advance. Tianjin transformation of coal-fired boilers, fast Boiler contributed.
Coal-fired steam boiler high quality in korea 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.
A boiler operation must be controlled and stable operation of secondary causes of boiler steam temperature control stability of a secondary steam temperature has important implications for safe and economic operation of the unit. When the steam temperature is too high, it can cause overheating, a portion of the metal to reduce the strength of the reheater, and the steam turbine pipe cylinder and a rotor, resulting in shortened life of the equipment. Severe over-temperature, it will also enable the heating surface blasting. When the steam temperature is too low, the effect thermodynamic cycle efficiency, and a steam turbine final stage blades at excessive humidity, severe water hammer may occur, resulting in damage to the blade fracture accidents. When the steam temperature substantially sudden rise dump, large thermal stress is generated in addition to the heating surface of each weld and the outer part of the boiler is connected, will cause the relative displacement between the cylinder and the rotor of the turbine increases, i.e., the expansion difference increases, severe or even static friction wheel and the separator, causing severe vibration. In addition both sides of the turbine steam temperature deviation is too large, both sides will uneven heating turbine, uneven thermal expansion. Therefore, the operation of the boiler steam temperature to closely monitor, analyze, adjust, control steam temperature stability with the most reasonable method.
