In recent years, China's environmental protection departments have been promoting the high effiency burning boiler "coal to gas" to reduce emissions, and win the Battle of the sky ", to coincide with the recent natural gas price, have not you transform coal-fired boiler, still What hesitate?
Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of high effiency burning boiler products, in March 2017 signed a six-ton steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
How to maintain the high effiency burning boiler shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.
Coal-fired high effiency burning boiler economizer economizer effect to save the name suggests is a secondary member of coal fired boilers and the like for the device, the principle is to use the coal-fired boiler economizer flue gas heat exchanger for heating the feedwater. Economizer heat absorbing smoke, reduced exhaust gas temperature, by improving the thermal efficiency of coal-fired boilers, to achieve the purpose of saving coal. Secondly, in the coal-fired boiler feedwater into the drum, since the exhaust gas after the preheating heater temperature increased, reducing the temperature difference between upper and lower walls of the drum, the drum reduces the thermal stress of the upper and lower walls coal-fired boilers, to reduce the vertical drum wall temperature difference due to damage, protect the safe operation of coal-fired boilers, coal-fired boilers to extend the life of the road.Free Chat
