Description

Smokeless coal-fired boiler

The utility model relates to a kind of boiler, particularly a kind of heat and smokeless coal burning boiler of using of heat supply water adopted.

In the prior art, the coal-burning boiler that is used for Cai Re and heat supply water is pure burning stove, general water sleeve type body of heater by steel, flame retardant coating in the body of heater, fire grate and hydroecium constitute, has the following ashpit that is provided with of positive furnace hearth and fire grate, such stove and accessory, the required air that burns 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 to have drained by smokejack again, thereby most smoke densities are big, even surpassed discharging standards, not only environment is caused severe contamination, and, wasted a large amount of energy because burning is insufficient.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of thermal efficiency smokeless coal burning boiler high, that Cai Re and heat supply water are used.

The purpose of this utility model can realize by following technical scheme: this thermal efficiency is high, adopt the smokeless coal burning boiler that heat and heat supply water are used, it comprises the cooking stove that furnace shell and interior flame retardant coating and fire grate thereof constitute, be arranged on the body of heater water heating casing in the cooking stove, be contained in the flue residue heat heat exchanger on the cooking stove, and described cooking stove has positive furnace hearth, back-fire stove hearth that communicates with positive furnace hearth and the ashpit that is positioned at fire grate bottom, positive furnace hearth have be contained in cooking stove on the last exhaust opening that is communicated with of the smoke uptake of flue residue heat heat exchanger, fuel mouth on back-fire stove hearth has, the air of offering on its sidewall is for mouth; And described body of heater water heating casing adopts hot-water line and left arch springing communicating pipe thereof, right arch springing communicating pipe, vault communicating pipe by arch---the heat build-up water tank constitutes, and the top of its heat build-up water tank is communicated with the bottom of flue residue heat heat exchanger on being contained in cooking stove.

The above-mentioned body of heater water heating casing who is arranged in the cooking stove is embedded in the flame retardant coating of furnace shell; Also can be that the bottom is embedded in the flame retardant coating of furnace shell and top is exposed in the stove hall.

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

Above-mentioned cooking stove, be positioned at its air for mouthful and push can also be provided with 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, can the supplemental oxygen pipe be inserted the fuel that is arranged in back-fire stove hearth for mouth by auxiliary air.

Above-mentioned cooking stove can adopt the low staged fire grate in preceding high back that is made of some grate plates.

Above-mentioned cooking stove can also be divided into the little cooking stove of independence that several all have positive furnace hearth, the back-fire stove hearth that communicates with positive furnace hearth and are positioned at the ashpit of fire grate bottom by dividing wall, makes then this boiler can operate at full capacity, also can partly work.

The above-mentioned dividing wall that is used for cooking stove is separated into several independent little cooking stoves, also can be embedded with heat-collecting device, this heat-collecting device can be adopted hot-water line and lower communicating tube constitutes by perpendicular putting, it is perpendicular put the upper end of adopting hot-water line and heat build-up water tank or by body of heater water heating casing's arch adopt that hot-water line is communicated with the heat build-up water tank, lower communicating tube be communicated with body of heater water heating casing's left and right sides arch springing communicating pipe.

The thermal efficiency provided by the utility model smokeless coal burning boiler high, that Cai Re and heat supply water are used is adopted hot water input and output pipe and temperature difference cyclic water tank and heating system with it and is connected, and have a bath sanitary water and heating supply water can be provided.

Heat and the smokeless coal burning boiler used of heat supply water adopted 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 carbon and imperfect combustion generated that burning is generated is through the burning fully again in back-fire stove hearth and the positive furnace hearth, generate carbon dioxide just through the cooking stove exhaust opening, the flue residue heat heat exchanger is drained, emit outside mouthful no burnt gas and the ashes fueling, therefore, this boiler suits to use the various cigarettes that have, smokeless solid fuel, compare with existing various pure burning boilers, because fuel has obtained burning fully, thereby thermal efficiency height, both reduced simultaneously pollution, saved a large amount of energy again environment.
