Abstract

The invention relates to a boiler with twice gasification combustion functions, which is characterized in that a gas generation furnace and a heat supply furnace are organically combined together; the fuel is preheated, dried, dehydrated, carbonized or coked, gasified and burned so as to precipitate volatile composition, tar and harmful gas during the first gasification combustion process. During the second gasification combustion process, the volatile composition, tar and harmful gas which are decapitated during the first gasification combustion process can be decomposed, gasified and burned further, thus having sufficient combustion, no black smoke and little dust. The boiler can be adaptable for the gasification combustion of powder-shaped mineral matter or biological matter fuel with large water content, non-uniform dimension, complex shape and low heat value, for the mixed gasification combustion of mineral matter and biological matter fuel, and even for the bodies or dejecta of the animals or kitchen garbage such as orts and the like, has strong adaptability to the fuel, thus being capable of disposing complex types. The boiler can be used as a civil boiler and is suitable for the burning disposal and utilization of daily garbage and medical garbage.

Description

Have two times of gasification combustion function and boiler that can eat " coarse cereals "
Technical field
The present invention relates to a kind of boiler that uses solid fuel, especially have two times of gasification combustion function and boiler that can eat " coarse cereals ".
Background technology
At present, known numerous boiler that uses solid fuel, do not have two times of gasification combustion function, can not use that water content is big, granule size differs, shape is mixed, mineral matter that calorific value is low and biomass fuel, simultaneously volatile matter, tar and the pernicious gas of being separated out in the combustion process can not get good treatment, and fuel combustion is insufficient flue dust, and environment is had pollution.
Summary of the invention
The purpose of this invention is to provide and a kind ofly have two times of gasification combustion function and boiler that can eat " coarse cereals ", it is that gas generator and heating heating boiler are combined, for the first time can carry out preheating, drying and dewatering, charing or coking, gasification, and combustion to fuel during gasification, and combustion, separate out volatile matter, tar and pernicious gas.Volatile matter, tar and the pernicious gas that the first time, gasification, and combustion was separated out further can be decomposed gasification, and combustion in the second time during gasification, and combustion, thus sufficient combustion, no black smoke, dust is few.The present invention can adapt to that water content is big, size differs, shape is mixed, the gasification, and combustion of Powdered low-calorie mineral matter or biomass fuel, also be fit to the mixing gasifying burning of mineral matter and biomass fuel, rubbishes from cooking such as corpse of animal or ight soil and leftovers, leftovers also can gasification, and combustion, adaptability to fuel is strong, can eat " coarse cereals " thus.Except that as the civil boiler, also be fit to the burning disposal and the utilization of house refuse, medical waste.

The specific embodiment
One, opens feed bin lid (4) fuel of packing into, light, after burner hearth progressively heats up, cover feed bin lid (4), pressure reduction appears in (also available air-introduced machine or air blast) in the burner hearth under the effect of chimney assembly (1), and gas begins to flow, anoxycausis district (Q1), combustion with meagre oxygen district (P1) and oxygen-enriched combusting district (F1) have progressively been formed, to giving birth to the stove success.
Two, at anoxycausis district (Q1), landing from top to bottom during fuel gasification combustion, and progressively combustion gasification, charing or coking from the bottom up successively, and separate out high-temperature vapor, volatile matter, tar and pernicious gas, form anoxycausis air-flow (Q2), anoxycausis air-flow (Q2) carries out secondary decomposition gasification, and combustion when passing through combustion with meagre oxygen district (P1), water vapour decomposes can produce hydrogeneous mixed gas.
Three, can suitably in feed bin (3), drip according to the difference (as coal) of using fuel, so not only reduce furnace temperature, reduce slagging scorification, can also produce hydrogeneous high heat and plant coal gas.
Four, at combustion with meagre oxygen district (P1), landing from top to bottom during fuel gasification combustion, the combustion with meagre oxygen air-flow (P2) of formation enters mixed combustion district (H).
Five, at oxygen-enriched combusting district (F1), landing from top to bottom during fuel gasification combustion, the oxygen-enriched combusting air-flow (F2) of formation enters mixed combustion district (H).
Six, fresh air enters mixed combustion district (H) through secondary wind inlet (12) by upright grid (11), high temperature heat that each road air-flow mixed combustion forms and heat-exchange tube (7) and interior bucket (9) carry out thermal energy exchange, cold water is from water inlet (10) input, and hot water is exported from delivery port (6).
Seven, the control valve of blast pipe (5) and secondary wind air inlet (12) and ash-digging gate (14) the big I of opening changes the oxygen supply coupling in the burner hearth, in order to regulating the combustion intensity of burner hearth, with the different needs that satisfies big fire, little fire, banks up a fire.
Eight, rotating grate (13), ashes fall, and fuel is also followed downward landing in the furnace chamber, can open feed bin lid (4) according to combustion case and add new fuel.
The present invention has: simple in structure, be easy to processing, low cost of manufacture; Easy to operate, easy to utilize; Adaptability to fuel is strong, and fuel source is extensive, and fuel price is low, economic operating cost.Face the earth and warm year by year, harm humans, each state all making great efforts energy savings, reduce discharging, so the present invention has good economic benefits and social benefit.
