Low discharging and high-energy effect novel industrial boiler

Abstract

The invention discloses a novel industrial boiler with low emission and high energy efficiency, and relates to the series of twenty boilers which are different in fuels and mediums, namely large-scale grate firing: scattered coal, moulded coal and biomass and chamber firing: fuel gas, oil-fired hot water, steam, phase-conversion heat exchange and distributed heat and power cogeneration boilers. The novel industrial boiler comprises a transverse boiler, a transversal and longitudinal container, a water wall tube, a vertical boiler shell, a thread smoke tube, and the like. The invention integrates the advantages of a water-tube boiler, a water-fire tube boiler and a corner-tube boiler, more particularly solves the different defects of three types of boilers; namely, the water-tube boiler has the defects of complicated technology as well as large volume and steel consumption; the water-fire tube boiler has the defects of tube plate crackle, tube explosion, smoke tube abrasion, and the like; the corner-tube boiler has the defects that the technology is complicated technology and the dust deposition at the tail part is difficult to be eliminated; and the invention also greatly improves the difficult problems of the three types of boilers that the initial emission concentration of smoke and dust is higher generally. The invention has the advantages of advanced installation technology and extremely obvious energy conservation and emission reduction.

Description

technical field [0001] The present invention relates to 20 boiler series with different fuels and different media, that is, large-scale layer combustion: loose coal, briquette, biomass and chamber combustion; gas, fuel oil hot water, steam, phase conversion heat and distributed heat and power cogeneration boilers . Background technique [0002] At present, the most popular industrial boilers in the domestic market can be classified into three types: [0003] The first large furnace type is water tube boiler, its main advantages are relatively stable and reliable operation, low failure rate, and small smoke and wind resistance. It is a type of furnace with the highest market share in the planned economy era or the early stage of market economy. Its main disadvantages are complex process, large volume, large steel consumption and high cost. [0004] The second largest furnace type is the water-fire tube boiler. Its main advantages are simple process, convenient manufacture a...

Problems solved by technology

Its main disadvantage is that the bending process of the flag-type structure is complicated and there are many partitions. Once the partition is installed with deviation, it is easy to cause water circulation accidents and it is difficult to find the fault point. The most prominent disadvantage is that the tail is seriously accumulated and difficult to remove.

[0006] The common disadvantage of the above three furnace types is that the initial emission concentration of soot is higher than the soot emission parameters of advanced countries in the world
