Abstract

The utility model relates to an energy-saving atmospheric boiler. The boiler hearth of the utility model is a double wall structure. The interior of the interlayer is provided with circulating water. The middle part of the boiler hearth is fixed with a smoke passage interlayer water baffle plate. The back part of the boiler hearth is uniformly distributed with convection flow discharge pipes by welding method. The interior of the smoke passage is welded with a vertical smoke pipe. The exterior of the vertical smoke pipe is the water storage of the outer partition layer of the smoke pipe. When in use, after the boiler hearth is ignited, the water of the double wall of the periphery of the boiler hearth is heated, the heat of the water enters the convection flow discharge pipes to be cyclically heated, and the heat is exhausted along the smoke gas. The stored water in the outer partition layer of the vertical smoke pipe is also heated. The heating area of the water is increased, and then the heat efficiency is improved.

Description

Power-saving normal-pressure boiler

The utility model relates to a kind of home-use power-saving normal-pressure boiler

At present, in the winter of north cold, the resident of inhabitation one-storey house adopts the heating of domestic heating stove mostly, promptly be commonly called as native heating installation, because this warming stove is to be provided with one group of comb to link to each other with steam heating pipe in traditional iron burner hearth, this warming stove can be a double-wall structure, because its heating surface area only limits to burner hearth, heating surface area is less relatively, and heating is not ideal enough.The utility model has designed a kind of power-saving normal-pressure boiler.

The utility model purpose is, the power-saving normal-pressure boiler of design, it is made up of burner hearth, shell, smoke-box etc., and this boiler is to improve on the basis of original native heating installation, it is made and has adopted water bag fire, fire to wrap the mode of water combination on the principle, all in the mode of water bag fire, being double-wall structure around the burner hearth in body of heater, is recirculated water in its interlayer, this power-saving normal-pressure boiler is simple in structure, easy to use, and thermal efficiency height, environmental pollution reduced.Characteristics such as this boiler has thermal efficiency height, and heating surface area is big, and heating speed is fast, and the interior pondage of boiler is big.

Power-saving normal-pressure boiler described in the utility model, this boiler in body of heater all in the mode of water bag fire, around the burner hearth is double-wall structure, its interlayer is a recirculated water, compares with existing domestic heating stove, and this boiler is easy to use, the room heating surface area is big, thermal efficiency height, heating speed is fast, and coal consumption is low relatively.

The power-saving normal-pressure boiler that the utility model provides, it is made up of shell, burner hearth, smoke-box, chimney etc., burner hearth is a double-wall structure, in its interlayer is recirculated water (10), two parts before and after burner hearth is divided into, its front portion is the combustion chamber, and the rear portion adopts the mode of welding to be fixed with laterally evenly distributed convection calandria (9), is the smoke-box expansion chamber in the below of convection calandria (9); Between the front and back of burner hearth, be fixed with flue layer folder water plate washer (14); Being fixed with vertical smoke pipe (4) in smoke-box, is interlayer water storage (5) between the smoke pipe (4), in a side of burner hearth, is respectively equipped with boiler hot-water outlet (6), water inlet (7) and water return outlet (8).

Referring to accompanying drawing

Fig. 1 is the utility model schematic diagram

Fig. 2 is the utility model side view cutaway drawing

Fig. 3 is the utility model vertical view

Further specify and provide embodiment below in conjunction with accompanying drawing

Power-saving normal-pressure boiler (see figure 1) described in the utility model, it is made up of shell, burner hearth, smoke-box, chimney etc., burner hearth is a double-wall structure, in its interlayer is recirculated water (10), two parts before and after burner hearth is divided into, its front portion is the combustion chamber, and the rear portion adopts the mode of welding to be fixed with laterally evenly distributed convection calandria (9), is the smoke-box expansion chamber in the below of convection calandria (9); Between the front and back of burner hearth, be fixed with flue layer folder water plate washer (14); In smoke-box, be fixed with vertical smoke pipe (4), between the smoke pipe (4) interlayer water storage (5), side at burner hearth, be respectively equipped with boiler hot-water outlet (6), water inlet (7) and water return outlet (8) in use, after igniting in the burner hearth, burner hearth is all with water heating in its double wall interlayer all around of mode of water bag fire, rising along with flame in the burner hearth, its heat enters convection calandria circulation heating, and flue gas enters flue and discharges the outer interlayer water storage of smoke pipe in the heating flue simultaneously behind convection calandria then; Water is entered in the cavity of burner hearth double-wall structure by water return outlet, discharge by the boiler delivery port again, thisly heat circularly and raise when burner hearth flue intraformational bed water temperature, so that reach the purpose of heating, the heating surface area of water is increased greatly, thereby improved the thermal efficiency.

Claims

1, a kind of power-saving normal-pressure boiler, it is made up of shell, burner hearth, smoke-box, chimney etc., it is characterized in that, burner hearth is a double-wall structure, in its interlayer is recirculated water (10), two parts before and after burner hearth is divided into, and its front portion is the combustion chamber, the rear portion adopts the mode of welding to be fixed with laterally evenly distributed convection calandria (9), is the smoke-box expansion chamber in the below of convection calandria (9); Between the front and back of burner hearth, be fixed with flue layer folder water plate washer (14); Being fixed with vertical smoke pipe (4) in smoke-box, is interlayer water storage (5) between the smoke pipe (4), in a side of burner hearth, is respectively equipped with boiler hot-water outlet (6), water inlet (7) and water return outlet (8).
