Abstract
The utility model relates to a steam boiler burning formed biomass fuels, which is characterized in that a hearth air distribution box is fixed into a boiler body and connected with a secondary air pipe seat, a plurality of air pipes are connected onto the hearth air distribution box, and a fuel air pipe is connected with a fuel feeding pipe. The steam boiler has the advantages of simple structure, sufficient burning, high heat efficiency, low emission, no pollution, low running cost and the like. Particularly, the biomass fuels are formed into grains with certain shapes by employing plant, farming and forestry residues such as straws, wood shavings, sawdust, cotton seed hulls and the like as raw materials through special process without adding any chemical additives. The biomass fuels convenient for burning are renewable energy resources, have wide sources, and not only can be renewably recycled, but also achieve the purpose of protecting environment.
Description
Technical field
The utility model belongs to field of boilers, is a kind of steam boiler of the moulding biomass fuel that burns.
Background technology
At present, employed boiler great majority are fire coal or natural gas in the society, coal or natural gas all are the non-renewable energy, because the high speed development of society, the energy starved problem is more and more serious, burning of coal is to cause coal-smoke pollution in addition, the main cause of sulfuric acid type acid rain and greenhouse gases effect, and clean energy resource is the task of top priority that solves atmosphere pollution.Biomass fuel is a kind of with plant and agriculture and forestry organic waste material, is raw material as stalk, wood chip, sawdust, cotton seed hulls etc., by special technology, do not add any chemical addition agent, make it to become the particle of definite shape, be convenient to burning, be a kind of regenerative resource, wide material sources.Biomass fuel is both renewable recycling, reaches the purpose of protection environment again, the SO after its burning
2, N
XThing is zero-emission almost, and residual ash content is few.
Summary of the invention
Goal of the invention of the present utility model is: provide a kind of thermal efficiency height, sufficient combustion, the novel biomass fuel vapour boiler plant of minimizing pollution, energy savings in the running.Technical solution of the present utility model is; A kind of biomass fuel steam boiler, form by boiler body, horizontal water tube, flue, leftover bits and pieces circle, fire grate, blast pipe, blast apparatus etc., it is characterized in that in boiler body, fixing a burner hearth matching air box, the burner hearth matching air box is connected with the secondary air channel seat, connecting several ajutages on the burner hearth matching air box, the fuel ajutage is connected with the fuel-feed pipe.The use the beneficial effects of the utility model are: have simple in structure, sufficient combustion, the high and low discharging of the thermal efficiency, pollution-free, characteristics such as operating cost is low, especially biomass fuel is a kind of with plant and agriculture and forestry organic waste material, as stalk, wood chip, sawdust, cotton seed hulls etc. is raw material, by special technology, do not add any chemical addition agent, make it to become the particle of definite shape, be convenient to burning, be a kind of regenerative resource, wide material sources.Biomass fuel is both renewable recycling, reaches the purpose of protection environment again.

The specific embodiment
Among Fig. 1 and Fig. 2, the utility model is by fire grate (21), by boiler body (6), hand hole (10), shoot door (22), feed pipe (11), water inlet base (20), water gage (1), impact tube (24), stop valve (2), safety valve (4), Pressure gauge (23), the blast pipe that is connected with blast apparatus (16), fuel ajutage (12), ring-type burner hearth matching air box (14), bearing (18), secondary air channel seat (15), blow-off pipe (17), horizontal water tube (9), flue (8), furnace gall head (7), shell end socket (5), Pressure gauge base (23), hoisting ring (25), get a foothold and enclose compositions such as (19).Feed pipe (11) is connected with automatic granular fuel conveying device.Fuel ajutage (12) is connected on the fuel-feed pipe (11), and communicates with fuel-feed pipe (11), and the other end of fuel ajutage (12) is connected with blast apparatus.Burner hearth matching air box (14) is being fixed in fire grate (21) top in the boiler body (6), and burner hearth matching air box (14) is connected with secondary air channel seat (15), and the other end of secondary air channel seat (15) is connected with blast apparatus in boiler body (6) outside.Connecting several ajutages (13) on the burner hearth matching air box (14), ajutage (13) is installed in the flue (8), and several openings (25) are arranged on the ajutage (13).
Among Fig. 3, the burner hearth matching air box (14) of ring-type is connected with airduct seat (15) with ajutage (13) and communicates.During use, constitute burner hearth by get a foothold circle (19), flue (8), burner hearth ajutage (13), flue (8) top is connected with the horizontal water tube (9) that is furnished with multilayer in furnace gall head (7), the flue and arranges, it is main heating surface.Under the drive of blast apparatus, blast pipe (16) and fuel ajutage (12) and secondary air channel seat (15) are blown in stove.The wind that blast pipe (16) is sent in fire grate (21) enters flue (8), makes biomass fuel go up burning at fire grate (21).The wind that fuel ajutage (12) is sent stirs the biomass fuel in fuel-feed pipe (11) enters flue (8), spreads to uniformly on the fire grate (21).The wind that is sent by secondary air channel seat (15), burner hearth matching air box (14) through ring-type is transported to ajutage (13), is entered in the flue (8) by the opening (25) on the ajutage (13) again, impels flame to produce rotary combustion in burner hearth, air-supply cube formula by this makes full combustion of fuel.
Claims (2)
1. biomass fuel steam boiler, it is characterized in that in boiler body (6), fixing a burner hearth matching air box (14), burner hearth matching air box (14) is connected with secondary air channel seat (15), connecting several ajutages (13) on the burner hearth matching air box (14), fuel ajutage (12) is connected with fuel-feed pipe (11).
