top class coal fired hot water boiler
Vertical steam boiler combustion characteristics combustion grate section with double action, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal. Gas steam boiler performance characteristics: 1, the furnace and comparing the old vertical boiler, heating area, rapid boost heating, less coal, high thermal efficiency, can save 25-30% of coal. 2, a furnace with multiple, user-friendly, the furnace can be used for the production of steam steaming canteens, disinfection tableware, bath heating, process steam, heating and the like locally heating the room. 3, the furnace with natural ventilation, induced draft fan and the blower does not need, no noise. 4, compact structure, installation, operation, easy maintenance, may be integrally handling, suitable flowability units. 5, heated with steam bath, food, heating, steaming, etc., pressure gauge scale strictly controlled within the design pressure, working pressure at any time shall not exceed the operating pressure. The scope of the steam boiler Application: can be used in textile, printing and dyeing, paper, food, rubber, plastics, chemicals, pharmaceuticals, iron and steel, metallurgy and other industrial products machining process required steam, and for enterprises, institutions, hotels, schools, restaurants, service industries such as heating, bath, air conditioning and hot water. Pledge: Since the equipment installation qualification pressure parts warranty 3 years, 12 months, auxiliary and lifetime maintenance, warranty period free of charge warranty for non-human failure (various defects caused by faulty equipment itself) of the Company, the replacement of damaged parts, the warranty period or man-made damage, is still responsible for maintenance and guidance equipment, for repair, replacement parts only fees. Quality assurance after the expiry responsible for maintenance of life.
How to protect the evaporation boiler reaches design: In order to stabilize the combustion, if the coal volatiles, reducing the amount of heat necessary to increase the excess air ratio, the boiler furnace flue gas temperature to be reduced and the amount of evaporated water wall decreases, the radiation furnace transducer heat formula indicates, the furnace flue gas temperature to reduce the influence of the radiation heat transfer is the fourth power of the relationship.
What impact have fuel moisture steam boiler? Most of the aqueous fuel when coal or heavy oil with steam atomization of entrained moisture in an amount not more than 5%, no effect on the coil and the inner shell boiler, the boiler because their materials are steel, steel are mainly: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng, with a strong antioxidant, water resistance. With more moisture, combustion performance worse, if the moisture up to 40% burn will be extinguished.
Winter heating season is approaching, Jinan City, Shandong Province in response to the country clean, low-emission environmental requirements, increase efforts to support the promotion of winter heating clean, clean heating to further enhance the city level, issued on the issue clean winter heating engineering and operational capital subsidy Notice.
Second, the use of centralized gas boiler user, uniform implementation of preferential gas prices 1.71 yuan / cubic meter, the heating period and after the end of the third-party audit of gas consumption, gas will be the final settlement price (not exceeding Municipality department approved between the reference price) and 1.71 yuan / cubic meter price difference subsidy to the gas company, to purchase heating companies use non-city franchise gas pipeline business gas heating can be direct subsidies to heating companies.
Third, the use of electricity users centralized heating, heating period and by the end of the third-party audit by the electricity, the power company will operate the unit with the settlement price and preferential rates (level of 0.5 yuan / kwh, Valley Electric 0.25 yuan / kilowatt the difference between the time) subsidy to operate the unit.
Fourth, the use of formula household heating boiler user, purchase subsidy subsidy to the user equipment or units in accordance with Standard 2000 underwritten yuan / household. Temporarily performed using the sub-family user heating boiler gas prices during the step, performed in accordance with a first gear price urban gas prices; after the heating period, gas operation subsidies subsidies to users according to standard 1200 / household .
Fifth, the use of household electric heating type user, can also get subsidies. Subsidy ranges: The air source heat pumps, domestic electric boilers, heating cables, heating the carbon crystal plate user. According to the notification, the device according to the purchase subsidy subsidized purchase truly carbon crystal plate does not exceed 2,000 yuan / household air-source heat pump, domestic electric boilers, heating cables subsidy standard is 2000 Yuan / or household user to Advancer units. After the heating period, power to the user according to operating subsidies subsidies 1200 / standard household.
