Abstract
The utility model relates to a firing the double -boiler section of thick bamboo boiler of living beings, providing a can effectively reduce boiler that nitrogen oxide discharged, it includes upper drum, lower drum, furnace, convection zone, furnace exit and convection zone directly link to each other, the convection zone is equipped with at least twice mid -feather, forms two at least flue gas return strokes. Among the above -mentioned technical scheme, owing to do not establish the firebreak, cancelled and fired the cinder room to just having increased furnace volume, just so having enabled fuel and fully burnt, the produced utilization ratio of heat radiation in furnace of fuel burning is higher, and furnace outlet temperature and exhaust gas temperature must correspondingly reduce, and nitrogen oxide's emission will reduce.
Description
Technical field
The utility model relates to a kind of double-drum boiler of biomass-burning.
Background technology
Existing pair of drum steam boiler all comprises burner hearth, burning chamber, convection section, and be wherein provided with firebreak between burner hearth and burning chamber, burning chamber is directly connected with convection section.The shortcoming of the boiler of this structure is: furnace exit temperature is high, high fume temperature, and the discharge capacity of nitrogen oxide is also high, can not reach better environmental requirement.
Utility model content
The purpose of this utility model provides a kind of double-drum boiler that effectively can reduce discharged nitrous oxides to overcome above-mentioned deficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of boiler that effectively can reduce discharged nitrous oxides, comprise upper drum, lower drum, burner hearth, convection section, described furnace outlet is directly connected with convection section, described convection section is provided with at least twice mid-feather, forms at least two flue gas backhauls.
In technique scheme, owing to not establishing firebreak, eliminate burning chamber, thus just increase combustion space, fuel so just can be made to be fully burned, the utilization rate of the heat radiation that fuel combustion produces in burner hearth is higher, and furnace exit temperature and exhaust gas temperature must correspondingly reduce, and the discharge of nitrogen oxide will reduce.
In one embodiment, described convection section is provided with three road mid-feathers, forms three flue gas backhauls.When convection heating surface amasss constant, by increasing a flue gas backhaul, just furnace exit temperature and exhaust gas temperature can be reduced further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Detailed description of the invention
A kind of boiler that effectively can reduce discharged nitrous oxides as shown in Figure 1, 2, comprise upper drum 1, lower drum 2, burner hearth 3, convection section 4, the outlet of described burner hearth 3 is directly connected with convection section 4, and described convection section 4 is provided with twice mid-feather 41, forms two flue gas backhauls.Also according to actual needs, three road mid-feathers 41 can be set at convection section, form three flue gas backhauls.
Claims (2)
1. one kind effectively can be reduced the boiler of discharged nitrous oxides, it is characterized in that: it comprises upper drum, lower drum, burner hearth, convection section, described furnace outlet is directly connected with convection section, and described convection section is provided with at least twice mid-feather, forms at least two flue gas backhauls.
2. a kind of boiler that effectively can reduce discharged nitrous oxides according to claim 1, is characterized in that: described convection section is provided with three road mid-feathers, forms three flue gas backhauls.
