Description
Technical field
This utility model belongs to boiler manfacturing field, specifically, particularly relates to a kind of single drum coal-firing efficient cleaning combustion boiler.
Background technology
Urbanization, industrialized development stimulate city steam supply, the increase of heat demand.As the infrastructure that city industrialization is important, concentrate steam supply, heat supply promoting to produce, environmental improvement and guarantee resident normally works, play the most important effect in terms of life.Traditional coal-burned industrial boiler compared with having that equipment is relatively low at large, systems technology is compared with the problem such as falling behind, coal quantity is poor, boiler efficiency is the highest, damage ratio is more serious, cause the waste of resource, and combustion process has been discharged a large amount of sulfur dioxide, nitrogen oxides, dust and other harmful gas, environment is caused severe contamination, is also the one of the main reasons forming haze weather.It is complicated generally to there is structure in existing single drum coal-fired boiler, and manufacture difficulty is big, and fuel tolerance is poor, easily dust stratification, flying dust and noise processed difficulty, boiler steel consumption is big, the shortcomings such as system power consumption is big, thus have impact on popularization and the application of single drum coal-fired boiler to a certain extent.
Summary of the invention
The purpose of this utility model is to overcome drawbacks described above, it is provided that a kind of single drum coal-firing efficient cleaning combustion boiler, and it arranges simple, compact conformation, good airproof performance, and boiler startup is rapid, and stand-by loss is little, and the in-site installation cycle is short, it is simple to safeguard.
Described single drum coal-firing efficient cleaning combustion boiler, including grate fired furnace, drum device and water-cooling system it is arranged in grate fired furnace, in grate fired furnace, lower section is provided with face arch and rear arch, anti-coking assembly it is provided with below described grate fired furnace, being provided with traveling-grate stoker below anti-coking assembly, the back-end surfaces at grate fired furnace rear is provided with flag formula passage heating surface, and flag formula passage heating surface is connected with air preheater and ash dropped unit by heating flue.
Further, described chain fire-gate front is provided with layering coal supply apparatus.
Further, described back-end surfaces is arranged over airtight fire door.
Further, described rear arch is provided with secondary air system.
Further, being provided with sealing device below described heating flue, sealing device is connected with ash dropped unit.
Further, described traveling-grate stoker is big wind cabin crossbeam type chain-grate.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model uses big wind cabin crossbeam type chain-grate, reasonable in design, scalable air distribution mechanism, and improve coal burns degree, it will be apparent that improves the uniformity of burning, thus greatly reduces boiler slag carbon content, makes coal leakage quantity be down to minimum simultaneously；
2, grate fired furnace is set up anti-coking assembly, effectively prevent both sides fire grate and expose and burn before flame；The face arch of short and the rear arch of lengthening, form semiclossed chamber structure, effectively prevent thermal loss, widened the adaptability of fuel；Meanwhile, rational secondary air system further ensures burning completely of fuel；
3, airtight fire door effectively prevents high-temperature flue gas from leaking, and improves the thermal efficiency；
4, the compound recycle mode that this utility model is unique, overcomes the Waterwall tube failure caused because of solid precipitation thing and boiler drum bottom wall and produces the accidents such as drum bleb damage because of metal superheat, it is ensured that boiler stable operation under various loads.
