Abstract
The utility model discloses a smokeless biomass and fuel coal dual-purpose boiler with a multistage chained grate, comprising a first combustion chamber and a second combustion chamber, wherein the first combustion chamber and the second combustion chamber are respectively connected with a water-heat exchange tube support through fire-passing linking channels, and the first combustion chamber is internally provided with two-stage chained grates. The two-stage chained grate has a two-stage grate induced-air back-combusting structure, and fuel which is not sufficiently combusted in the first-stage chained grate can be continuously combusted on the second-stage chained grate, thus, efficient and sufficient combustion is realized and the combustion efficiency is increased. The fire passing linking channel is in a spiral raising structure by which temperature can be effectively gathered together so that a high-temperature turbulent flow is formed; and the water-heat exchange tube support adopts a multi-back-stroke water-fire exchange way, heat air is in multistage perturbation and forms the turbulent flow in the exchanging process, and thus, dust can be effectively reduced, and the dust removal effect can be improved.

Background technology
For existing plain cylindrical furnace, under the situation that does not increase cleaner, the discharging of its flue dust can't reach national boiler emission standard.Present most of chain type fire grates, efficiency of combustion is low, and fuel combustion has not exclusively often just emitted.And common biomass fired boiler produces tar and acidic materials owing to can't realize high-temp combustion completely to fuel when causing fuel combustion, goes down to damage boiler for a long time, has reduced service life, reduces the boiler hot conduction efficiency.The utility model provides the smokeless biomass-burning of multistage chain type fire grate coal-fired boiler for dual purpose just to the problems referred to above of existing boiler, has realized that the multipolarization of chain type fire grate is used, and has improved the efficiency of combustion of fuel, has reduced the discharging of pollutant.
The utility model content
To the defective that exists in the prior art, the purpose of the utility model is to provide the smokeless biomass-burning of a kind of multistage chain type fire grate coal-fired boiler for dual purpose, through this boiler, improves the efficiency of combustion of fuel, reduces the discharging of pollutant.
To achieve these goals, this uses the technical scheme of novel employing following:
The coal-fired boiler for dual purpose of the smokeless biomass-burning of multistage chain type fire grate; Comprise first combustion chamber and second combustion chamber; First combustion chamber is connected with second combustion chamber through port; Be provided with first order chain type fire grate and second level chain type fire grate in first combustion chamber, first combustion chamber is connected with extreme misery heat exchange pipe support through the second level link passage that overdoes, and overdoes through the first order and link passage and be connected with extreme misery heat exchange pipe support in second combustion chamber.
Further, the coal-fired boiler for dual purpose of the smokeless biomass-burning of aforesaid multistage chain type fire grate, first combustion chamber and inside, second combustion chamber are square structure.
Further, the coal-fired boiler for dual purpose of the smokeless biomass-burning of aforesaid multistage chain type fire grate, said first order link passage and the second level interface channel that overdoes that overdoes is the spiral lift structure.
Further, the coal-fired boiler for dual purpose of the smokeless biomass-burning of aforesaid multistage chain type fire grate, the water-cooling wall of said boiler is pipe support and square chest structure combining.
Further again, the coal-fired boiler for dual purpose of the smokeless biomass-burning of aforesaid multistage chain type fire grate, said extreme misery heat exchange pipe support is many backhauls combination of essence and spirit replace tubes frame, is provided with heat conduction baffle between the adjacent pipe support.
Further, the coal-fired boiler for dual purpose of the smokeless biomass-burning of aforesaid multistage chain type fire grate, said boiler is provided with charging aperture and cleaning door.
The effect of the utility model is: the described boiler of the utility model, and adopt multilayer level chain type fire grate to draw the anti-sintering structure of phoenix, effectively prolong the fuel combustion path; Two rank chain type fire grate can make fuel realize completing combustion, and its unique spiral structure that overdoes forms the high temperature turbulent flow; The burning of realization fuel-efficient, many backhauls heat-exchange tube shelf structure effectively strengthens heat exchanging process; Fully heat absorption and dedusting, making this boiler not add cleaner can be up to state standards.
