Abstract

The utility model relates to field of boilers, i.e. energy-saving environment protection steam boiler.It includes the burner hearth in furnace wall, it is characterised in that upper furnace connects tube bank, and smoke box is connected in tube bank, and smoke box connects tube bank, such multiple-layer stacked, until connecting outlet flue；Space is water holding space between tube bank, smoke box and furnace wall, which has water inlet, water outlet, steam (vapor) outlet.Air-introduced machine is had on outlet flue.Using fire tube bundle, smoke box overlaying structure, reduce the speed of pyrotechnics outflow burner hearth, extend through the time, so that full combustion of fuel, reach energy conservation, reduce pollution, conducive to the purpose of environmental protection.Increase simultaneously and water engaging surface product in water holding space, are conducive to heat water, the raising thermal efficiency.

Description

Energy-saving environment protection steam boiler

Technical field

The utility model relates to field of boilers, i.e. energy-saving environment protection steam boiler.

Background technique

In the prior art, boiler includes burner hearth, the water jacket on water pipe and hearth wall in burner hearth, and burner hearth has smoke Mouthful, the disadvantage is that burning is insufficient, flue gas is big, not environmentally.

Utility model content

The purpose of this utility model is in view of the above deficiencies and provides that a kind of combustion efficiency is good, pollutes low energy conservation and environmental protection and steams Boiler furnace.

The technical solution of the utility model is: energy-saving environment protection steam boiler, including the burner hearth in furnace wall, feature exists It connects and restrains in upper furnace, smoke box is connected in tube bank, and smoke box connects tube bank, such multiple-layer stacked, until connecting outlet flue；Pipe Space is water holding space between beam, smoke box and furnace wall, which has water inlet, water outlet, steam (vapor) outlet.

Air-introduced machine is had on outlet flue.

The utility model has the advantages that: 1, fire tube bundle, smoke box overlaying structure were used, the speed of pyrotechnics outflow burner hearth is reduced Degree, extended through the time, increases cigarette and burns the time, makes pyrotechnics full combustion in it, reduces pitch-black cigarette and excludes, realizes and save Coal reaches energy conservation, reduces pollution, is conducive to environmental protection.2, tube bank, smoke box overlaying structure directly heat water, increase and water Water engaging surface product in space, heat dissipation area is big, so that heat sufficiently conducts, improves the thermal efficiency.

The embodiments of the present invention is described in further detail below in conjunction with attached drawing.

Detailed description of the invention

Fig. 1 is the utility model structure diagram.

Specific embodiment

Referring to Fig. 1, parts title is as follows: furnace wall 1, burner hearth 2, tube bank 3, smoke box 4, outlet flue 5, water holding space 6, water inlet Mouth 7, water outlet 8, steam (vapor) outlet 9, air-introduced machine 10, deashing thorax 11.

Referring to Fig. 1, energy-saving environment protection steam boiler, curve is cutting line, exposes its interior structure, it includes the furnace in furnace wall 1 Thorax 2(is combustion chamber, band fire door).The tube bank spaced smoke pipe of 3(is connected on 2 top of burner hearth, and tube bank the inside communicates with burner hearth 2, flows Pyrotechnics is crossed, tube bank outside is contacted with the water in water holding space 6), the space that 3 connection mono- bigger pyrotechnics of smoke box 4(of tube bank passes through), Smoke box 4 connects tube bank 3(and communicates with each other), such multiple-layer stacked (being three layers in Fig. 1, more layers is arranged according to furnace body size), Until connecting outlet flue 5；Space is water holding space 6 between tube bank 3, smoke box 4 and furnace wall 1, the water holding space 6 with water inlet 7, Water outlet 8, steam (vapor) outlet 9.Air-introduced machine 10 is had on outlet flue 5.The utility model can be industrialized for warming oneself or producing steam Or it is civilian.

Working principle: pyrotechnics enters tube bank 3 in burner hearth 2, draws until outlet flue 5 through air-introduced machine 10 entering smoke box 4. Period heats the water in water holding space 6, produces steam or hot water.

It is described above, only specific embodiment of the present utility model, various illustrations are not to the reality of the utility model The limitation of matter Composition of contents.
