Biomass burning grate hot water boiler is a single boiler cylinder longitudinal fire tube boiler, combustion equipment for the grate. Thewaterwallonthe left andright sidesofthe furnace is the radiant heatingsurface,andthethreadedsmokepipeinthetwowingsofthe furnaceandthecylinderistheconvectionheatingsurface.Theboiler body adopts the form of upper cylinder, water wall tube and collecting box symmetrical arrangement on the overall structure. The barrel is welded by the barrel body and the front and rear tube plates. The furnace layout of the boiler is reasonable and the combustion efficiency is high.
The boiler adopts a variety of environmentalprotectionmeasures,suchasclothbagdustremoval, twin tower desulfurization, so that the boiler soot emission to meet the national environmental standards.The boiler adopts arch tube plate and threaded smoke pipe, which not only increases heat conduction, but also solves the problems of tube plate cracking, waterwallexplosion,lowthermalefficiency,insufficientoutput,poor adaptabilityof coalquality andsoon.
1. The boiler drum is composed of an arched tube plate and a threaded smoke pipe, which changes the structure of the boiler drum from a quasi rigid body to a quasi elastic body, eliminates the tension support in the tube plate area, and reduces stress. The smoke tube inside the tube plate has been changed from two returns to a single return, solving the problem of tube plate cracks.
2. Due to the arrangement of a rising tube row at the bottom of the drum, the stagnant water area at the bottom of the drum is eliminated, making it difficult for sludge to deposit. The high-temperature area of the drum can be well cooled, preventing bulging at the bottom of the drum.
3. The use of threaded smoke pipes has achieved enhanced heat transfer effects, achieving the characteristics of fast boiler temperature rise and pressure rise, and improving the thermal efficiency of the boiler.
4. Compact in structure, compared to similar boilers, it has a smaller overall size and saves investment in boiler room infrastructure.
5. Stable operation, convenient adjustment, and sufficient output.
6. The octagonal wall inside the furnace and the outlet smoke window have a certain dust reduction effect. The original dust concentration of the boiler is controlled below the standard, ensuring that the smoke and dust emissions of the boiler meet the national environmental protection regulations.
