Abstract

The utility model discloses a boiler. The utility model is characterized in that the smoke chamber of the existing boiler is changed into that the smoke chamber comprises an upper smoke chamber and a lower smoke chamber; the upper smoke chamber is provided with an upper heat pipe and the lower smoke chamber is provided with a lower heat pipe which is introduced into a hot water chamber; the inner wall of the hearth is provided with a steam generator which can provide combustion supporting for generator and remove dust.

Description

A kind of sluggard's boiler

The utility model relates to civilian normal-pressure hot-water boiler, especially a kind of sluggard's boiler that need not staff on duty.

In the prior art, be disclosed No. 88203587 patents of Patent Office of the People's Republic of China with the most approaching technology of the utility model.This patent also is a kind of sluggard's stove, surrounds hot hydroecium, boiling water chamber, burner hearth and smoke-box by furnace body wall and constitutes, and its hot hydroecium is around smoke-box, and the boiling water chamber is around burner hearth.But smoke-box and burner hearth all are conventional structures, and therefore, it is still not ideal enough also just to have the thermal efficiency, and oke exhaust blackness and dust exhausting concentration still do not reach the problem of national requirements.

The purpose of this utility model, be exactly at the existing in prior technology weak point, and on its basis, smoke-box and burner hearth improved, to improve its thermal efficiency, to reduce oke exhaust blackness and dust exhausting concentration, constitute a kind of sluggard's boiler technology scheme that need not staff on duty.

This programme is realized by following technical measures.Mainly be to surround sluggard's boiler that hot hydroecium 7, boiling water chamber 16, burner hearth 11 and smoke-box constitute by furnace body wall 8 for heat-insulation layer 1.The characteristics of this programme are that described smoke-box is made up of last smoke-box 4 and play smoke-box 2, and heat pipe 5 feeding hot hydroecium 7 on two are housed in last smoke-box 4 at least, and two following heat pipes 3 feeding hot hydroecium 7 also are housed in playing smoke-box 2 at least; Other is provided with steam generator 14 in a side of the inwall outlet flue 9 of burner hearth 11.This programme also has following concrete characteristics, and promptly the bottom of smoke-box 4 has ash hole 18 to stretch out furnace body wall 8 on described.And have ash hole 19 to stretch out furnace body wall 8 in the bottom of following smoke-box 2.14 of described steam generators are that a vaporizer 15 is arranged, and connect snakelike steam guiding tube 13 thereon, have steam drain 12 and communicate with burner hearth 11 on top layer steam guiding tube 13.

In this programme, smoke-box is repacked into upper and lower two smoke-boxes and is added with heat pipe, make the heat of smoke-box obtain better utilization.Have again and in burner hearth, installed the steam added combustion device additional, fuel is fully burned in burner hearth and has reduced the discharging of flue dust.These two improvement, just make that the sluggard's boiler that constitutes with this programme does not in use need staff on duty, twenty four hours only need add twice bunker coal, get final product boiling water without interruption and hot water, and than similar stove fuel saving more than 30 percent, the thermal efficiency can reach 80%, and its oke exhaust blackness and dust exhausting concentration all are lower than national standard under the situation of normal combustion.This shows, the utility model compared with prior art, its effect is conspicuous.

Description of drawings:

Fig. 1 is the part sectional structure schematic diagram of the utility model embodiment;

Fig. 2 is that A-A of Fig. 1 is to cross-sectional schematic.

Below by a specific embodiment and in conjunction with its accompanying drawing, the utility model is further elaborated.Sluggard's boiler surrounds hot hydroecium 7, boiling water chamber 16, burner hearth 11 and the smoke-box of being made up of last smoke-box 4, following smoke-box 2 by the furnace body wall 8 for heat-insulation layer 1 and is connected with impact tube 6.Around smoke-box is hot hydroecium 7, and hot hydroecium 7 communicates with furnace body wall 8 water supply tank 17 outward, and is boiling water chamber 16 around burner hearth 11, is stamped coal filling hole lid 10 on the coal filling hole of burner hearth 11.Heat pipe 5 feeding hot hydroecium 7 on four are being housed on the roof on the last smoke-box 4, and the bottom side wall of last smoke-box 4 has ash hole 18 to stretch out furnace body wall 8.Four following heat pipes 3 also are housed on roof on the following smoke-box 2 feed hot hydroecium 7, the bottom side wall of following smoke-box 2 has ash hole 19 to stretch out furnace body wall 8.Other is provided with a steam generator 14 in a side of the inwall outlet flue 9 of burner hearth 11, and 14 of this steam generators are that a vaporizer 15 is arranged at the bottom, connect snakelike steam guiding tube 13 on it, have steam drain 12 and communicate with burner hearth 11 on top layer steam guiding tube 13.
