Abstract
The utility model discloses a low-nitrogen oil/gas-fired boiler, and belongs to the field of manufacturing of boilers. The low-nitrogen oil/gas-fired boiler mainly comprises a boiler body, and is characterized in that a burner is arranged at the front end of the boiler body; a hot air channel is formed on the tail of the boiler body; a wave-shaped furnace pipe is arranged in the boiler body; a back smoke chamber is formed between the wave-shaped furnace pipe and the hot air channel; a blower is connected with the back smoke chamber through a cold air channel. The low-nitrogen oil/gas-fired boiler is compact in structure, steam and hot air can be supplied for drying raw materials, particles which are not burned completely in flue gas are burned more fully, and the emission of nitrides is reduced greatly. The low-nitrogen oil/gas-fired boiler is mainly applied to the processing of gypsum boards and deep processing of wood.
Description
Technical field
The utility model belongs to boiler and manufactures field, specifically, relates in particular to a kind of low nitrogen fuel-oil or fuel-gas boiler.
Background technology
In at present domestic some middle-size and small-size plasterboard processing enterprises and wood deep processing industry, in production, not only need a large amount of steam, also need the hot flue gas of certain parameter to carry out drying material.Therefore, enterprise is when procuring equipment, generally to utilize steam boiler that steam is provided, arrange that in addition hot-blast stove provides the hot blast of certain thermal power, in the situation that enterprise can need steam and this two kinds of thermals source of hot blast simultaneously, can provide a kind of steam that can provide can provide the thermal hardware of hot blast again, but at present also not for such present situation, successfully develop low nitrogen, high efficiency fuel (gas) boiler of steam, hot blast dual-purpose.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of saturated vapor that certain pressure can be provided that the low nitrogen fuel-oil or fuel-gas boiler of hot blast can be provided again, has realized the multipurpose of single equipment.
Described low nitrogen fuel-oil or fuel-gas boiler, comprises boiler body, it is characterized in that: boiler body front end is provided with burner, and boiler body afterbody is provided with hot-flow flue, is provided with corrugated flue in boiler body, between corrugated flue and hot-flow flue, is provided with rear smoke chamber; Air blast is connected with rear smoke chamber by cold air duct.
Compared with prior art, the beneficial effects of the utility model are:
The utility model compact conformation, by corrugated flue heat exchange meeting, produce the saturated vapor under certain pressure, high-temperature flue gas enters rear smoke chamber, user's temperature as required, by air blast, in rear smoke chamber, sneak into cold wind, utilize mixing wind to heat and material drying, and the particle not burning in flue gas is burnt more fully, simultaneously, in rear smoke chamber, sneak into cold wind, further reduced the fire box temperature in rear smoke chamber, making the burning of fuel in rear smoke chamber is low-temperature burning, burn more abundant, greatly reduce the discharge capacity of nitride.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model front view;
Fig. 2 is the structural representation of the utility model left view.
In figure, 1, burner; 2, boiler body; 3, corrugated flue; 4, rear smoke chamber; 5, cold air duct; 6, hot-flow flue; 7, air blast.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A low nitrogen fuel-oil or fuel-gas boiler, comprises boiler body 2, and boiler body 2 front ends are provided with burner 1, and boiler body 2 afterbodys are provided with hot-flow flue 6, are provided with corrugated flue 3 in boiler body 2, between corrugated flue 3 and hot-flow flue 6, is provided with rear smoke chamber 4; Air blast 7 is connected with rear smoke chamber 4 by cold air duct 5.
The utility model in use, hot-flow flue 6 is connected with the device of material to be dried, during work, take oil or gas as fuel, fuel is after burner 1 spray burning, through corrugated flue 3 heat exchange, can produce the saturated vapor under certain pressure, the high-temperature flue gas of generation enters after rear smoke chamber 4, user uses enthusiasm condition according to oneself, by air blast 7 regulate sneak into rear smoke chamber 4 cold blast rate number, obtain temperature required lower hot blast rate, be used for heating and material drying; In rear smoke chamber 4, sneak into cold wind, further reduced the fire box temperature in rear smoke chamber 4, make material is low-temperature condition when burning, simultaneously, in rear smoke chamber 4, strengthen air capacity, the particle not burning in flue gas is burnt more fully, effectively reduce the discharge capacity of nitride in flue gas.
