Szl Series Assembled Coal Fired Hot Water Boiler
90 t/h coal fired circulation fluidized bed boiler is a natural circulation water tube boiler with double cross drums. Fuel is sent to the furnace from stoker and it is mixed with air from equal pressure air chamber, the flow gas produced from it burned goes upside into horizontal cyclone separator.
Steam boiler rules Henan fast boiler with small series to introduce the company's steam boiler operating procedures. First, the components of the steam boiler before oven cooking oven and check (a) and oven cooked boiler furnace must be checked in detail. Check the following items: 1, cold chain grate test more than 24 hours, cold test should meet the following requirements: (1) grate should be smooth turning chain wheel axle, found arched, two tension bolts can be tightened. (2) the active grate sprocket good occlusion. Minimum gap (3) on both sides of the active grate block with the side seal and the side seal angle not less than 6 mm. Distance (4) on both sides of both ends of the furnace grate platoon leader pin in the sprocket should be kept equal. If it is found at one end to the occurrence of side friction, long waist-hole may be a tap with a hammer, the end surfaces on both sides remains equal distance. (5) steam boiler grate rotated without jamming, deviation phenomenon, when the deviation found by the inspection hole into the rear grate tail, the tie bolt align the two bearings of the drum, deviation phenomenon can be eliminated. The boiler has ignition combustion, still need to transfer found Hearth n, just before two adjustable chain tensioning bolt shaft directly outside the furnace, but preceded align the front sprocket shaft and a gearbox connect the safety pin or bolt removed until after squaring shaft to a gearbox with a chain alignment pin or bolt after tightening, may otherwise result in misalignment with the sprocket shaft of a gearbox and mechanical damage. (B) Check broken grate furnace platoon leader pin is bent, if long waist hole in the furnace may be carried out at any time platoon leader pin alignment reload. (C) a chain grate does not allow foreign matters (such as bolts, nuts, nails and other iron) is present. (D) firing door open and flexible, easy to open and drop the shutter coal, coal gate left and right side of the grate surface distance equal to, the thickness of both sides of the seam to ensure equal furnace, as a method for reducing ranging from links available to make equal, coal shutter cover plate should cover tightly to prevent leakage into the coal, coal stuck shutter. (Five) of each grate windshield of smoke damper and damper adjustment inside the flue flexible switch. (Vi) blower, Fan, Java machine, commissioning normal water supply equipment. (Vii) manhole, hand hole is tight, attached parts fitted Ge are complete. (Viii) the furnace wall is normal, the flue is tight. (Ix) steam boiler pipes, water pipes, sewage road is complete. (J) all filled with lubricating oil in the bearing housing and oil cup. (Xi) All electrical equipment should be empty running test, inspection equipment, and other electrical lines is intact.
Vertical steam boiler introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. 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.
In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
