Abstract

The utility model discloses a high burning-value energy-saving multi-purpose coal stove which can be used as a vertical and desk coal stove for family and restaurants and portable stove for picnic barbecue and chafing dish. The stove inner sleeve of the high burning-value energy-saving multi-purpose coal stove is an integral structure. An arch-shaped porous reflective heat-collecting plate whose inner surface is coated with paint which can generate infrared ray is covered on the upper part of the stove sleeve with a secondary air inlet hole. When coal combusts in the high burning-value energy-saving multi-purpose coal stove, harmful gases which is generated during the process of coal combustion are enforcedly combusted by the secondary air inlet hole and the arch-shaped porous reflective heat-collecting plate, and the thermal efficiency of the coal and the ignition temperature of the stove are increased. The high burning-value energy-saving multi-purpose coal stove has the advantages of coal saving, quick ignition, high temperature, and long fire banking time.

Description

High burning-value energy-saving multi-purpose coal stove

The utility model is a kind of high burning-value energy-saving multi-purpose coal stove.

Existing honeycomb briquette stove commonly used partly is made up of furnace shell, interior cover, thermal insulation layer, bell, air port etc.Honeycomb briquette stove commonly used in use, from igniting begin to coal combustion to the greatest extent till, the needed intake difference of each stage burning.But existing honeycomb briquette air inlet size is fixing, so when causing the coal igniting and during fast after-flame, institute's wind supply quantity is excessive, and the unhappy or not anti-burning of promptly getting angry, but when coal combustion, because the wind supply quantity deficiency easily produces more pernicious gas, these pernicious gases can not burn again.The thermal efficiency of stove is descended.According to measuring and calculating, the thermal efficiency of general coal stove only has about 10%.In addition, coal stove used in everyday, big, the Heavy Weight of volume is not suitable for carrying outdoor barbecue and as the hot pot stove use of the hall of elegance.

Task of the present utility model provides a kind of quick combustion, the pernicious gas forced burning that produces in the time of can be with coal combustion, and can work as the high burning-value energy-saving multi-purpose coal stove that hot pot stove uses.

The utility model is by bell, furnace shell, interior cover, thermal insulation layer, air port and arch form porous reflection heat collector panel, compositions such as secondary intake opening.Cover is the overall structure of diatomite compacting sintering wherein.Secondary intake opening is arranged around burner hearth, be stamped an arch form inner surface in upper end, exit, secondary intake opening top and scribble the porous reflection heat collector panel that can produce infra-red paint.Be stamped a bell in lower end, exit, secondary intake opening top, use when banking up a fire.Have the air rise hole at burner hearth bottom and be connected with the air port, the number of air rise hole, shape, structure are identical with honeycomb briquette.The solid section on air rise hole top has the convex step.

The utility model is owing to increase secondary intake opening around burner hearth, and added a cover the reflection heat collector panel in exit, secondary intake opening top upper end, the pernicious gas enforcing reflection second-time burning that coal is produced in combustion process, it is more abundant to burn, the firepower longer duration.When banking up a fire, add a cover a bell in lower end, secondary intake opening exit, banking is saved the energy for a long time.This furnace construction is reasonable, because cover is overall structure in the stove, so can be made into hot pot stove and picnic oven.

Another improvement of the utility model is that the secondary intake opening air intake is to be connected with the stove shell external world, so the intake of forced burning and stove air port size are irrelevant, the replenish air amount is big, overheavy firing, furnace temperature height.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is A-A ' cut-away view of the present utility model.

Fig. 3 is a reflection heat collector panel schematic diagram of the present utility model.

According to Fig. 1, Fig. 2, Fig. 3, the utility model is made up of cover (8), thermal insulation layer (10), air port parts such as (1) in bell (15), furnace shell (7), the stove.Wherein cover (8) is to form with the whole compacting sintering of diatomite in the stove.Burner hearth (16) in the stove in the cover (8) has secondary intake opening (11) on every side, and the air intake (4) of secondary intake opening (11) directly is communicated with furnace shell (7) outside.A castiron circular arch type porous reflection heat collector panel (14) is stamped in cover (8) upper end, secondary intake opening (11) exit (13) on every side in stove, and reflection heat collector panel (14) inner surface scribbles and can produce infrared ray brown iron oxide coating.Cover (8) lower end, secondary intake opening (11) exit (13) on every side is stamped a castiron bell (15) in addition in stove.The burner hearth (16) of cover (8) bottom has air rise hole (5) in stove, and air rise hole (5) is connected with air port (1).Shape, number and the structure of air rise hole (5) are identical with the honeycomb briquette hole.Solid section in air rise hole (5) has convex step (6).In furnace shell (7) bottom pad pin (2) is arranged, handle (9) is housed on furnace shell (7) top.

When opening stove, during coal combustion, the air that enters from air port (1) rises up in the burner hearth (16) from air rise hole (5), because coal cinder is filled up by the convex step (6) of air rise hole (5) solid section, can not influence flowing of air.Portion of air rises to the exit (13) on burner hearth (16) top from secondary intake opening (11) through preheating in addition, plays the oxygenating second-time burning.Coal does not partly fire the pernicious gas rising in combustion process runs into reflection heat collector panel (14) bounce-back, infra-red paint on the reflection heat collector panel (14) can produce infrared ray, increase the ignition temperature on burner hearth (16) top, make this part pernicious gas force second-time burning.Can improve the fuel value of coal cinder so greatly, make coal combustion more abundant, the energy has obtained utilizing fully.So the utility model quick combustion, ignition temperature height, firepower longer duration.

As when banking up a fire, bell (15) to be covered the coal cinder of locating in the stove at secondary intake opening exit (13) lower end step (12) can not get air, slowly spontaneous combustion can prolong fire-sealing time.
