Description

Normal pressure living beings rolling fire grate hot-water boiler

Technical field

The utility model relates to a kind of normal pressure living beings rolling fire grate hot-water boiler in boiler energy-saving industry.

Background technology

At present, CLHG, the CLSG vertical water-tube fire-tube boiler of the most manufacturing enterprises of China boiler manufacturer production, originally all adopted dual fixed grate, this kind of boiler due to simple in structure, to account for floor space little, be convenient to manufacture and install therefore there is stronger vitality for Small Civil; But because this kind of boiler thermal output is low, exhaust gas temperature, dust concentration are high, as large in increased the high height of heating surface and cleaner cost and floor space at afterbody, lose simple in structure, to account for floor space little, is convenient to the advantage manufacturing and install, therefore operability is not strong; Especially adopt fixed grate, during firing biomass fuel, combustion product is pasted fire grate, and burning cannot normally be carried out.Therefore develop a kind of normal pressure living beings rolling fire grate hot-water boiler is the scientific research task of expecting solution always.

The purpose of this utility model is to provide a kind of normal pressure living beings rolling fire grate hot-water boiler, and this boiler design science is novel, it is simple to manufacture, cost is low, floor space is little, it is efficient, energy-conservation, clean to reach and simple process, operating cost is low, boiler normal pressure is safe and reliable to operation.

Utility model content

The purpose of this utility model is achieved in that a kind of normal pressure living beings rolling fire grate hot-water boiler, whole device is by rectangle shell, rectangle flue, upper smoke-box, lower smoke-box, exhanst gas outlet, auxillary flue, atmospheric communicating pipe, water outlet base, water inlet base, Pressure gauge, give wind apparatus, charging gear, spur roller gear fire grate, horizontal water tube, the first convection tube, the second convection tube, the 3rd convection tube forms, by rectangle shell, the inside and outside rectangle cylindrical shell that forms of rectangle flue, the first convection tube, the second convection tube, the 3rd convection tube respectively with upper smoke-box, lower smoke-box connects, horizontal water tube is connected with flue left and right sides, exhanst gas outlet is connected with smoke-box under outside, auxillary flue is connected with rectangle flue top, atmospheric communicating pipe, water outlet base, Pressure gauge is connected with rectangle shell top, water inlet base is connected with rectangle shell rear lower, be connected to wind apparatus with rectangle shell left plate, charging gear inserts and is connected with the front bottom of rectangle shell, spur roller gear fire grate is vertically installed in rectangle shell bottom.

Main points of the present utility model are its structure.Its operation principle is, combustion system is that biomass fuel is transported to fuel on gear type travel(l)ing grate through charging gear, at rectangle flue internal diameter, to wind apparatus, regulate and fully burn, combustion product gases comes downwards to smoke-box through horizontal water tube to the first convection tube and through the supreme smoke-box of the second convection tube, comes downwards to lower smoke-box and enter chimney through exhanst gas outlet, and that auxillary flue causes is outdoor (during interim blowing out with); Hot user's backwater footpath water inlet base enters in stove, and water at low temperature is being sent into hot user through heating by water outlet base, forms the circulatory system.Atmospheric communicating pipe on body of heater is connected to system expansion tank and guarantees the operation of security of system normal pressure.

Normal pressure living beings rolling fire grate hot-water boiler compared with prior art has design science novelty, technique is easy to manufacture, floor space is little, exhaust gas temperature is low be down to 150 ℃ of following, boiler normal pressure operations, safe and reliable, realize use clean energy resource and energy-efficient, retain vertical boiler volume feature little, that floor space is little have realized horizontal form, be convenient to arrange heating surface and furnace insulation, employing profile of tooth rolling fire grate solves the advantages such as problem that biomass fuel is pasted fire grate, will be widely used in boiler energy-saving industry.

Accompanying drawing explanation

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment:

With reference to accompanying drawing, a 1. normal pressure living beings rolling fire grate hot-water boiler, whole device is by rectangle shell 1, rectangle flue 2, upper smoke-box 3, lower smoke-box 4, exhanst gas outlet 5, auxillary flue 6, atmospheric communicating pipe 7, water outlet base 8, water inlet base 9, Pressure gauge 10, give wind apparatus 11, charging gear 12, spur roller gear fire grate 13, horizontal water tube 14, the first convection tube 15, the second convection tube 16, the 3rd convection tube 17 forms, and it is characterized in that: by rectangle shell 1, inside and outside rectangle cylindrical shell, the first convection tube 15 of forming of rectangle flue 2, the second convection tube 16, the 3rd convection tube 17 respectively with upper smoke-box 3, lower smoke-box 4 connects, and horizontal water tube 14 is connected with flue 2 left and right sides, and exhanst gas outlet 5 is connected with smoke-box under outside 4, and auxillary flue 6 is connected with rectangle flue 2 tops, atmospheric communicating pipe 7, water outlet base 8, Pressure gauge 10 is connected with rectangle shell 1 top, water inlet base 9 is connected with rectangle shell 1 rear lower, be connected to wind apparatus 11 with rectangle shell 1 left plate, charging gear 12 inserts and is connected with the front bottom of rectangle shell 1, and spur roller gear fire grate 13 is vertically installed in rectangle shell bottom.

Below in conjunction with embodiment, the utility model is further described in detail:
