Description
Technical field
The invention belongs to coal-fired combustion equipment field, it is related to a kind of coal-fired cooking and heating furnace and cooking heating method and use
On the way, more particularly to a kind of energy-saving environment protection fire coal cooking and heating furnace theoretical based on fractional combustion and cooking heating method and purposes.
Background technology
At present, the family of northern China certain areas, particularly small towns and country residentses, generally using native heating heating,
Due to the design not science of cooking stove, part coal can not completely burn and be discharged with cigarette, and utilization rate is low, not only coal consumption amount
Greatly, and serious pollution can be caused to air.Also, in real life, numerous rural subscribers are while heating, it is also desirable to
Stove can be used and cooking simultaneously, such as heated up water, cooked and cooking.
At present, domestic stove mainly has two kinds of coal-fired forms on the market：
It is positive to burn stove (Fig. 1 (a))：I.e. traditional is most simply also most common direct combustion mode, flame during solid fuel ignition
Propagated along the natural flow direction of heat smoke, combustion intensity is high, and firepower is prosperous, can meet user's cooking demand.The positive stove that burns is applied to nothing
The low fuel of the volatile matters such as bituminous coal.Although just burning stove with good cooking ability, using bituminous coal dispersion coal or using bituminous coal as
During the moulded coal that raw material is made, heating of being heated after being added due to fire coal, Volatile is discharged, volatile matter is difficult to immediately with flue gas
After-flame, causes a large amount of black smokes (tar, CO, VOC, sulphur and nitrogen oxide etc.) and people's smell of choking to be emerged, severe contamination environment.
Reverse burning furnace (Fig. 1 (b))：I.e. solid fuel ignition when the burning side that propagates of the natural flow direction of flame backheating flue gas
Formula, the characteristics of with that can delay Volatile speed, furnace temperature is high, burning is abundant, can substantially eliminate black smoke, it is adaptable to bituminous coal etc.
The high fuel of volatile matter.Because counter combust uses many backhaul designs to improve after-flame degree more, firepower is weaker, therefore its is unsuitable
For cooking, it can only warm oneself, it is difficult to which by part, common people receive；Simultaneously because planning whole burner hearth is in oxygen-enriched high-temp combustion,
Discharged nitrous oxides concentration is higher.
For problem present in conventional oven, people, which work out, can be applied to the civil of cooking and heating simultaneously

Flow flue, forms multiple backhauls, causes firepower weak, and excessive internal heat speed is slow, is not suitable for cooking, it is impossible to meet cooking and heating
Double duty.
And the conventional stove for cooking heating substantially still falls within positive burning stove when carrying out cooking, different from traditional
Positive to burn stove, the volatile matter that it separates out fire coal burns before being discharged with flue gas by Secondary Air, reduces blackness of the exhaust.But such as
, will be by switching pull bar to heating state before each coal shown in Fig. 3, and then make stove interior state change of burning during coal larger
(strong and weak and pollutant the discharge capacity of such as firepower).Also, gasification furnace is still " positive to burn " in cooking, during using bituminous coal cooking
Still smolder, the problem of dusty gas is discharged is not solved fundamentally.
