Description

Vertical non-smoke boiler

The utility model relates to a kind of vertical boiler, particularly a kind of vertical less boiler.

Existing vertical boiler, be pure burning stove, generally by the water sleeve type body of heater that side is fueled mouthful that is provided with of steel, fire grate and fire tube or water pipe type furnace roof heat exchanger constitute, has the following ashpit that is provided with of positive furnace hearth and fire grate, such stove and accessory, the burning required air enters the stove hall by ashpit through fire grate, the carbon that burning is generated, the carbon monoxide that imperfect combustion generated has little time to burn fully just by the furnace roof heat exchanger again, the stove and accessory impact tube has been drained, thereby the thermal efficiency is low, smoke density is big, such boiler not only environmental pollution is serious, but also because fuel combustion is insufficient, the waste ample resources.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the vertical less boiler that a kind of fuel combustion is abundant, the thermal efficiency is high is provided.

The purpose of this utility model can realize by following technical scheme: this fuel combustion is abundant, the vertical less boiler that the thermal efficiency is high, it comprises that anti-burning furnace shell and interior flame retardant coating and water sleeve type thereof are just burning the cooking stove that body of heater and interior flame retardant coating and fire grate thereof constitute, just burning body of heater with water sleeve type is provided with all-in-one-piece and is just burning the furnace roof heat exchanger, anti-burning furnace shell and water sleeve type are just burning the fixing assembling of body of heater, and the cooking stove that constitutes has positive furnace hearth, the back-fire stove hearth that communicates with positive furnace hearth and be positioned at the ashpit of fire grate bottom, back-fire stove hearth are provided with fuels mouth, the air of offering on its sidewall is for mouth.

Above-mentioned cooking stove can also be offered on the back-fire stove hearth sidewall of corresponding its back-fire stove hearth bottom again and push red charcoal mouth.

Above-mentioned cooking stove, be positioned at its air for mouthful and push can also be provided with again on the back-fire stove hearth sidewall between red charcoal mouth several auxiliary airs for mouthful, dispose that several heads stop up and the supplemental oxygen pipe that offers a series of apertures on the sidewall, during use, the supplemental oxygen pipe is inserted the fuel that is arranged in back-fire stove hearth for mouth by auxiliary air.

Above-mentioned fire grate can adopt fixed grate; Also can adopt reciprocal grate; Can also adopt chain furnace grate.

Above-mentioned just burning furnace roof heat exchanger, can by water heating casing and its inboard a series of Dou put and two ends communicate with the water heating casing adopts hot-water line, be used for quirk is set to "

" dividing plate of shape passage constitutes; Also can adopt vertical fire tube type furnace roof heat exchanger; Can also adopt vertical water pipe type furnace roof heat exchanger.

Above-mentioned just burning furnace roof heat exchanger for reducing outlet temperature, further reducing dust emission concentration, can also impact tube bottom within it be provided with falling dust room, set up the dedusting umbrella.

Vertical less boiler provided by the utility model, simple in structure, cost is lower, the burning required air is to enter the stove hall by the air of offering on the back-fire stove hearth sidewall for mouth, bottom at back-fire stove hearth, fuel obtains just being taken fire by the airborne oxygen that its top enters, the carbon monoxide that burning carbon and the imperfect combustion of generating generates is through the burning fully again in back-fire stove hearth and the positive furnace hearth, generate carbon dioxide just through just burning the furnace roof heat exchanger, the stove and accessory impact tube is drained, thereby, compared with prior art: have thermal efficiency height, dust emission concentration is minimum, environmentally safe, economize on resources, also fueling the advantage of emitting outside mouthful no burnt gas and the ashes, suiting has cigarettes in that the use of various places is various, smokeless solid fuel.
