The utility model discloses a kind of low-BTU gas efficient burning boiler, including boiler body, be positioned at the burner on the left of described boiler body and be positioned at the air preheater on the right side of described boiler body；Described boiler body include cylinder, be positioned at the flue inside described cylinder, be positioned at lower left burning gases interface, be positioned at bottom-right return combustion chamber, the second backhaul smoke pipe above, be positioned at the 3rd backhaul smoke pipe above described second backhaul smoke pipe, be positioned at left side front smoke box and be positioned at right side rear smoke box；Described air preheater is connected by a flue and described boiler body.Beneficial effect: low-BTU gas, due to steady flame difficulty, the most directly discharges, causes huge energy waste, by this Project-developing, can directly be burnt by boiler, save operating cost for enterprise.
Description
Technical field
This utility model relates to boiler technology field, particularly relates to a kind of low-BTU gas efficient burning boiler.
Background technology
Low calorific value gas fuel generally refers to calorific value gaseous fuel between 2800 ~ 6280kJ/m3, industrial belonging to low calorific value gas fuel such as blast furnace gas, coal seam gasification coal gas, the various gasifier gas etc. of integral coal gasification, its calorific value just corresponds to the 1/10 ~ 1/8 of heating value of natural gas.The main component of blast furnace gas is CO and N2.Wherein CO is colourless, tasteless toxic gas.The content of every cube of blast furnace gas CO is about 0.5kg.By present GB 3095-2012 " ambient air quality ", the CO daily mean of concentration that its three grades of air quality standards specify is 6mg/m3.Every m3 blast furnace gas be enough to the CO content making 20,000 m3 air more than three grades of air quality standards, and serious environment pollution affects health.
Low-BTU gas composition with system operation conditions change thus calorific value is unstable, other be correlated with Wuli-Shili-Renli system approach also can change.Such as directly burning, heat power equipment is stablized properly functioning impact the biggest.Therefore being usually present such situation, low combustion value furnace gas can only discharge, and contained energy runs off and environmental pollution.
Utility model content
In view of the foregoing, this utility model provides a kind of low-BTU gas efficient burning boiler.
For reaching above-mentioned purpose, this utility model solves its technical problem and be the technical scheme is that
A kind of low-BTU gas efficient burning boiler, including boiler body, is positioned at the burner on the left of described boiler body and is positioned at the air preheater on the right side of described boiler body；Described boiler body include cylinder, be positioned at the flue inside described cylinder, be positioned at lower left burning gases interface, be positioned at bottom-right return combustion chamber, the second backhaul smoke pipe above, be positioned at the 3rd backhaul smoke pipe above described second backhaul smoke pipe, be positioned at left side front smoke box and be positioned at right side rear smoke box；Described air preheater is connected by a flue and described boiler body.
Its further feature is as follows:
Described air preheater bag is provided with hot-flow flue and cold air duct.
Due to the utilization of technique scheme, this utility model compared with prior art has a following beneficial effect:
1. low-BTU gas is due to steady flame difficulty, the most directly discharges, causes huge energy waste, by this Project-developing, can directly be burnt by boiler, save operating cost for enterprise.
2. the content of every cube of blast furnace gas CO is about 0.5kg.By present GB 3095-2012 " ambient air quality ", the CO daily mean of concentration that its three grades of air quality standards specify is 6mg/m3.Every m3 blast furnace gas be enough to make the CO content of 20,000 m3 air, and more than three grades of air quality standards, serious environment pollution affects health.By this Project-developing, meet national standard by the exhaust emissions after boiler combustion.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model a kind of low-BTU gas efficient burning boiler.
Detailed description of the invention
Below in conjunction with specific embodiment, content of the present utility model is described in further detail:
Refering to Fig. 1, a kind of low-BTU gas efficient burning boiler, including boiler body, it is positioned at the burner 1 on the left of described boiler body and is positioned at the air preheater 11 on the right side of described boiler body；Described boiler body include cylinder 6, be positioned at the flue 3 inside described cylinder, be positioned at lower left burning gases interface 2, be positioned at bottom-right return combustion chamber 4, the second backhaul smoke pipe 7 above, be positioned at the 3rd backhaul smoke pipe 8 above described second backhaul smoke pipe, be positioned at left side front smoke box 5 and be positioned at right side rear smoke box 9；Described air preheater is connected by a flue 10 and described boiler body.Described air preheater bag is provided with hot-flow flue 12 and cold air duct 13.
1., for the feature design large-scale combustion room that low calorific value gas fuel exhaust gas volumn is big, combustor, than conventional increase 20%, the boiler structure of high circulation area, adjusts afterbody waste-heat recovery device way of recycling, keeps boiler to have higher efficiency；
2. according to the change of the composition of low calorific value gas fuel, add a certain amount of H2, one or more of CO, CH4, make the burning can be with even running；Meanwhile, flame combustion chamber central temperature to be controlled, within 1500 DEG C, reduces the generation of NOx, to reach the optimum of combustion system；
3. increase boiler tail UTILIZATION OF VESIDUAL HEAT IN, the temperature to more than 200 DEG C of combustion air is greatly improved, it is beneficial to the burning of low calorific value gas fuel and reduces heat loss due to exhaust gas, it is remarkably improved the operational efficiency of heating equipment, makes boiler efficiency grade meet and exceed two grades of Energy Efficiency Standards that TSG G0002-2010 " boiler energy-saving technical supervision rule of management " specifies.
Above-described embodiment is only for illustrating technology of the present utility model design and feature; its object is to allow person skilled in the art will appreciate that content of the present utility model and to be carried out; protection domain of the present utility model can not be limited with this; all equivalence changes made according to this utility model spirit or modification, all should contain in protection domain of the present utility model.
