Abstract

The invention relates to a cooker which has two-pass gaseous combustion function and can use various fuels. The fuel can be dried and dehydrated, preheated, carbonized, coked and gasified, the volatile matter, the tar and the harmful gas are separated out during the primary gas gaseous combustion. The volatile mater, the tar and the harmful gas separated out during the primary gaseous combustion are further decomposed, gasified and combusted during the secondary gaseous combustion; therefore, the combustion is sufficient, no black smoke is generated and the dust is little. The invention is applicable to the gaseous combustion of pulverous lower-calorific-value mineral matters or biomass fuels with big water content, different sizes and various shapes; the cooker is also applicable to the gaseous combustion of the mixture of mineral matters and biomass fuels, namely, animal corpse or feces and orts, leftovers and other kitchen wastes can also be gasified for combustion; therefore, various fuels are applicable to the cooker.

Description

Have two times of gasification combustion function and cooking stove that can eat " coarse cereals "
Technical field
The present invention relates to a kind of cooking stove that uses solid fuel, especially have two times of gasification combustion function and cooking stove that can eat " coarse cereals ".
Background technology
At present, known numerous cooking stove 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 cooking stove that can eat " coarse cereals ", can carry out drying and dewatering, preheating, charing, coking, gasification to fuel during gasification, and combustion for the first time, 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 life use stove kitchen range, also be particularly suitable for the burning disposal and the utilization of house refuse, medical waste.

The specific embodiment
One, fuel is packed into from charge door (3), lights, and after burner hearth progressively heats up, covers feeding cover (4), and burner hearth has progressively formed anoxycausis district (Q1), combustion with meagre oxygen district (P1) and oxygen-enriched combusting district (F1), to giving birth to the stove success.
Two, at anoxycausis district (Q1), can slide from top to bottom during fuel gasification combustion, and progressively combustion gasification, charing or coking from the bottom up successively, separate out volatile matter and tar and pernicious gas, dehydrate, pre-heating temperature elevation, the pressure in anoxycausis district this moment (Q1) increases, the anoxycausis air-flow (Q2) that the volatile matter of separating out, tar and pernicious gas and water vapour form is passed down through top, combustion with meagre oxygen district (P1), upwards enters mixed combustion district (H) again.Anoxycausis air-flow (Q2) carries out secondary decomposition gasification, and combustion when passing through combustion with meagre oxygen district (P1).
Three, at combustion with meagre oxygen district (P1), can slide from top to bottom during fuel gasification combustion, the combustion with meagre oxygen air-flow (P2) of formation upwards flows into mixed combustion district (H).
Four, at oxygen-enriched combusting district (F1), can slide from top to bottom during fuel gasification combustion, the oxygen-enriched combusting air-flow (F2) of formation upwards flows into mixed combustion district (H).
Five, fresh air enters mixed combustion district (H) through tertiary air import (10), and the flame that each road air-flow and fresh air mixed combustion form sprays through passage of flame (5).
Six, all imbed magnet in main air intake (19), secondary air register (11) and the tertiary air door (12), air door is adsorbed on the body of heater (1) by magnetic force, move adjusting main air intake (19), secondary air register (11) and tertiary air door (12) respectively and can change the oxygen supply coupling, regulate combustion intensity, with the different needs that satisfies big fire, little fire, banks up a fire.
Seven, the labyrinth sand seal connects, and is filling thin sand and soil in maze trough, and this is simple in structure, and sealing is reliable, and is easy to use, prevented that effectively flue gas is excessive.
Eight, can wave grate (15) and wave grate axle (16) and fixedly connected, rotate and wave grate axle (16) and make and can wave grate (15) and wave, ashes fall, and fuel is also followed downward landing in the furnace chamber, can open feeding cover (4) as required 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.
