Vertical coal fired steam (hot water) boiler
The LSG / H coal-fired steam boiler series products for vertical coal-fired steam pipe. The hot water boiler, design two kinds of bituminous coal. The structure of the boiler comprises a boiler body, a grate, piping, valves, instruments, equipment, etc. the chimney foundation; the boiler body is mainly composed of U ring, drum, head, furnace, furnace head, horizontal pipe, flue, convection tube bundle components in compression and so on, the head of the pot shell manhole, convenient for boiler maintenance and cleaning. The horizontal pipe type LSH vertical cross tube boiler furnace body is arranged for the convection heating area, furnace grate tube and the lower part of the stove body is arranged in the heat radiation area, structure of furnace and flue gas flow, reasonable layout, compact structure, convenient operation and maintenance. Advanced combustion technology of LSH type vertical cross tube boiler, coal combustion on the grate from the door into, gas in the internal furnace by water pipe and dust erosion, staggered fine carbon black containing in the flue gas, are multi bundle cutting falls on the grate again after two times of burning. LSH series boiler beam circular flow route: pot near the furnace, furnace top, horizontal pipes and upright tube heated water vapor amount is larger, the proportion of small and upward mobility; near shell water heating, steam consumption, the proportion of large flows downward, thus forming water cycle. LSH series boiler flue gas process is: high temperature flue gas generated by the combustion of coal on the fire grate, the rising edge of the furnace, scouring the transverse water pipe, furnace and cupola tube, will quickly pass the heat inside the boiler water, smoke rising scouring convection tube bundle, and chimneys, because of back flow flue gas cycle can reach smoke the effect of residual gas and dust, through the chimney into the atmosphere.
Horizontal pipe has three functions: first, increase the heating surface of the boiler; second, it is conducive to the water cycle in the boiler.
Vertical coal-fired steam boiler:
1, boiler design, manufacturing, supervision and inspection in strict accordance with the "steam boiler safety supervision regulations," JB/T 10094-2002 "industrial boiler general technical conditions", JB/T 1619-2002 "shell boiler manufacturing technology", to ensure the long-term stability of boiler. The furnace compared with the old vertical boiler, large heating area, boost, ceasefire fast, compact structure, small occupied area, strong output, high thermal efficiency, smoke prevention and dust control standards, the steam quality is good, the steam temperature reaches 150-180, the overall handling of the move, investment in infrastructure, convenient operation and maintenance. 2, make full use of flue gas flowing longitudinally convection heating surface, improve the thermal efficiency of the boiler, boost heating fast, less coal consumption, high heat efficiency, coal saving 25-30%; 3, the furnace using natural ventilation, does not need the air blower and the fan, no noise, due to smoke more than the return to nature more on the purpose of dust Globalink 4, save energy. The production of gas, boiler operation, strict control in the design of pressure within the pressure scale, working pressure shall not exceed the operating pressure at any time; 5, a multi-purpose, convenient user, can also burn coal burning wood. The production of steam furnace can be used to provide gas for industrial production and daily life, canteen steaming, tableware disinfection, bath heating, washing and ironing machinery industry, food industry, food industry, bio chemical industry, automobile industry, oil, steam cleaning, hot water supply, school mixing station bridge, railway, highway, high-speed railway bridge, concrete curing maintenance, national key project of Beijing-Shanghai high-speed railway, shiwugao iron, Zheng West high iron, high iron, Lanzhou Guiyang Guangzhou high-speed rail, Daguang Expressway, steam, heating units for the production of small and medium enterprises.
