Abstract

The utility model discloses a cooking water heating energy-saving boiler. Four water pipes (9) with closed upper and lower openings are vertically arranged between a water jacket of a boiler body (7) and the water jacket of a hearth (8) in the boiler, thereby dividing space between the water jacket of the boiler body (7) and the water jacket of the hearth (8) into four back-fire flues (31); and the back-fire flues (31) are communicated with a lower flue (10) communicated with a chimney (6), the water pipes (9) are all communicated with the water jacket of the boiler body and the water jacket of the hearth, the bottom part of each water pipe is higher than the boiler bottom, the upper end of each water pipe is higher than a water jacket port (11) of the hearth, and a cover plate (12) is arranged thereon. Smoke and fire in the boiler return back from top to bottom, water in the four water pipes, the water jacket of the boiler body and the water jacket of the hearth fully absorb the residual heat in the smoke and the fire during the back-smoke process, thereby further improving the thermal efficiency and achieving the purpose of energy conservation. Furthermore, the smoke and the fire return back from the top to the bottom, and pulverized coal in the smoke and the fire naturally falls to the boiler bottom, thereby greatly reducing the emission of the pulverized coal and playing the environmental protection role.

Description

Cooking hot-water heating power economized boiler

Technical field

The utility model relates to a kind of boiler.

Background technology

Existing most of cooking hot water space heating boilers adopt burner hearth to last outlet flue, arrive the fume exhausting type of chimney more more, directly high temperature pyrotechnics are discharged in the air, both fail high efficiency and utilized heat energy, waste the energy, caused a large amount of coal dusts to drain in the air again, caused serious air pollution.

Summary of the invention

The purpose of this utility model is to provide a kind of cooking hot water space heating boiler of energy-conserving and environment-protective.

Technical solution adopted in the utility model is, this cooking hot-water heating power economized boiler, comprise bell, water inlet pipe, outlet pipe, the ashes door, stove rod plate, chimney, the water pipe of four upper and lower opening sealings vertically is set between furnace water jacket and hearth water sleeve, they are separated into four with the space between furnace water jacket and the hearth water sleeve and return fiery flue, return fiery flue and be connected with lower flue that chimney is communicated with, four equal and furnace water jackets of water pipe, hearth water sleeve is connected, its bottom is high from furnace bottom, the upper end exceeds the hearth water sleeve mouth, and on establish cover plate, cover plate, hearth water sleeve mouth and four water pipes constitute four smoke-refeed mouths.

Owing to taked technique scheme, so pyrotechnics of the present utility model is to return from top to bottom, in returning the cigarette process, four water pipes, body of heater fire are overlapped and hearth water sleeve in water fully absorb waste heat in the pyrotechnics, further improve the thermal efficiency, reach energy-conservation purpose.Moreover pyrotechnics returns from top to bottom, and the coal dust in the pyrotechnics just drop to furnace bottom naturally, significantly reduced to drain into airborne coal dust dust quantity, played environmental-protection function.
