Abstract

The utility model discloses an energy-saving boiler comprising a cover (1), a door (2), a grate bar disc (3), a chimney (4), a water outlet pipe (5) and a water return pipe (6), wherein a liner water jacket (8) is arranged in a boiler body water jacket (7), both the liner water jacket and the boiler body water jacket are communicated with each other through an upper arc water jacket (9) and a lower annular water jacket (10); an annular smoke return flue (11) is formed between the boiler body water jacket (7) and the liner water jacket (8); an upper opening of the annular smoke return flue (11) is provided with an arc cover plate (24) and reserved with a smoke return opening (12); the annular smoke return flue (11) is communicated with a smoke outlet (13) at the rear part of the boiler body; and the smoke outlet (13) is communicated with the chimney (4). In the boiler, the thermal energy of high-temperature smoke is fully absorbed by the water in the water jackets around the boiler body when the smoke moves around the annular smoke return flue so as to improve the thermal efficiency and save energy; and during the return of the smoke, the dust sinks to the flue rather than being directly discharged to the air so as to reduce pollution and realize environmental protection.

Description

Power economized boiler

Technical field

The utility model relates to a kind of normal-pressure boiler.

Background technology

At present, most boilers all are to take the mode of directly smoke evacuation that the high temperature cigarette is entered in the atmosphere, contain a large amount of heat energy in the high temperature cigarette on the one hand, lose in vain and cause energy waste.Contain a large amount of dust in the high temperature cigarette on the other hand, enter in the atmosphere, cause environmental pollution.

Summary of the invention

The purpose of this utility model is to provide a kind of power economized boiler of environmental protection.

Technical solution adopted in the utility model is, this power economized boiler, comprise bell, fire door, stove rod plate, chimney, outlet pipe, return pipe, one inner bag water jacket is set in the burner hearth of furnace water jacket, the two is connected through last arc water jacket and following ring-shaped water jacket, and looping smoke returning flue between furnace water jacket and the inner bag water jacket is established curved cover plate and stayed and establish smoke-refeed mouth in that annular smoke returning flue is suitable for reading, the annular smoke returning flue is communicated with the outlet flue that the body of heater rear portion is provided with, and outlet flue communicates with chimney.

Owing to taked technique scheme, so after the utility model boiler furnace pyrotechnics goes upward to the fire door place, meet bell and stop, force it to carry out annular smoke returning flue from smoke-refeed mouth, detour half cycle from annular smoke returning flue after, enter the chimney discharge by outlet flue.Its advantage is, in annular smoke returning flue detours process, and the heat energy of high temperature pyrotechnics, the water in the water jacket that is surrounded up and down fully absorbs, and has effectively improved the thermal efficiency, has saved the energy; Moreover high temperature pyrotechnics returning down in the process that detours, and wherein a large amount of dust sinks in flue, avoids directly entering in the atmosphere, has reduced pollution, has reached the environmental protection purpose.
