Abstract

The utility model discloses a new coal stove whose retorting chamber and burning chamber are reversible and continually-usable, comprising 2, 3, or 4 furnace chambers with the same structure. An air-passed bridge is arranged among the furnace chambers. The furnace chambers can be used as the retorting chamber and the burning chamber in turn. The effect of the utility model can be better when the bituminous coal is burned in the coal stove. The bituminous coal can be burned with no smoke evacuation, having better effect of decontamination than the honeycomb briquette that is ignited at the upper part. With two furnaces, the utility model uses less coal than the common coal stove with one furnace. The utility model solves the problems of continuously adding coal, continuously use and damping down at night of the coal stove with the mode of igniting at the upper part.

Description

Reversible type continually-usable coal stove

The utility model relates to the cooking stove of briquet, particularly a kind ofly can make the shaped coal of bituminous coal smokeless combustion, and destructive distillation, burning locellus reversible use type coal stove continuously.

Smoke abatement and dust control, saving coal is the main purpose of transforming various cooking stoves.Use moulded coal dedusting is effectively economized on coal, and the energy-conservation and environmental benefit that particularly goes up honeycomb briquet lighting and cooking stove thereof is very remarkable, can accomplish the bituminous coal smokeless combustion.But present last ignition honeycomb briquette furnace can not reach continuous stoking, uses continuously, and igniting agent is the cost height not only, and has pollution, and fully burning is desirable not enough.

The purpose of this utility model is to provide a kind of continuous stoking of advantage ， And energy with last ignition honeycomb briquette furnace, the continuous use, and without the type coal stove of igniting every day, it can eliminate the pollution of igniting agent basically, the abundant ideal more of burning, dust removing effects is better.

The invention is that a kind of destructive distillation, burning locellus reversible use type coal stove continuously.It is constructed as shown in Figure 1, among the figure, and (1) heat collector panel or heat collector, (2) burner hearth, (3) tile, (4) secondary air register, (5) secondary air duct, (6) ring-type air compartment, (7) secondary air hole, (8) air-through bridge, (9) flow splitter, (10) external thermal insulation, (11) coal-carrying ring, (12) air chamber, (13) furnace shell, (14) dividing plate, (15) chimney, A are left hearth, and B is a right bearth.

Fig. 2 is the heat collector profile, among the figure, and the overheated ring of (16) water conservancy diversion, (17) passage of flame, (18) thermovent.Heat collector has changed the writing board shape that has flame hole of original heat collector panel, has better heat build-up effect.

The utility model has two burner hearth (2) A chamber and B chambers as shown in Figure 1 that structure is identical at least, has air-through bridge (8) to communicate between the burner hearth. Fill the heat-barrier material such as slag wool between tile (3) and the furnace shell (13) as external thermal insulation (10). Inwall at the burner hearth middle part is established flow splitter (9), and flow splitter is provided in a side of the groove depression that burner hearth sidewall Si Zhou And leads to air-through bridge, and is flammable in order to dredge Gas. Secondary air duct (5) one ends lead to secondary air register (4), and an end leads to ring-type air compartment (7). The ring-type air compartment be located at tile outside around, communicate with secondary air hole on the tile. Burner hearth bottom has coal-carrying ring (11), is air chamber under the coal-carrying ring, and air chamber is a wind air intake place, doubles as grey thorax. Burner hearth installation heat collector panel suitable for reading is preferably installed effective heat collector (1).

The utility model has the identical burner hearth of the structure more than two or two, when a burner hearth (as the A chamber) is done the combustion chamber high temperature use, seal another burner hearth (B chamber) as the destructive distillation chamber, with coal particularly the volatile matter that produces of low-temperature decomposition of bituminous coal import combustion chambers burn by air-through bridge, avoided energy waste and pollution.After the A chamber burns down, can be with the B chamber as the combustion chamber, this moment, B chamber retort process was finished, and can not produce smoke pollution.Can give A chamber coal after use the B chamber, exchange use has like this solved long-term use, and the problem of spending the night of banking up a fire has also solved the pollution problem of each igniting.Destructive distillation, burning locellus are separated out more fully than the low temperature volatile matter of the coal stove of a burner hearth, active ingredient more can the completing combustion utilization, and ignition honeycomb briquette furnace can improve 5% on the thermal efficiency ratio.

In order to strengthen result of use, available housing surrounds fire door, adds pyrosphere on the housing, Huo Gai, And install chimney (15), and chimney plays exhausting and puts a chimney on the stove and make the fire draw, and makes firepower more violent.Shown in Fig. 3 square coal stove and Fig. 4 A-A profile, when using square combined type moulded coal, can be designed to the rectangle burner hearth, And row piles up the several piece moulded coal, establishes two air-through bridges (8) between two Room.In coal kitchen range utilization rate high place such as dining room, available this programme principle, 3～4 burner hearths are set respectively has air-through bridge to communicate, and can use 2～3 kitchen range eyes simultaneously.

It mainly is two furnace chambers that the reversible that is used for family uses the moulded coal stove continuously, though be that two burner hearths are coaling, because sufficient combustion, than also economizing on coal with big normal cellular coal stove.Through test, as only warming oneself and heat up water, diel is with 4 in coal, and common stove and accessory will burn 6～7 in coal, and it is economized on coal and anti-pollution is tangible.If use its better effects if of shaped coal of bituminous coal.

Claims

1, a kind of destructive distillation, burning locellus, reversible uses type coal stove continuously, it is characterized in that having at least 2 burner hearths (2) that structure is identical, there is air-through bridge (8) to communicate between the burner hearth, each inboard wall of burner hearth has flow splitter (9) to lead to air-through bridge, tile has ring-type air compartment (6) outward, and the ring-type air compartment communicates with secondary air hole on the tile, communicates with secondary air duct (5) again.

2, use type coal stove continuously according to the described reversible of claim 1, it is characterized in that, available housing surrounds fire door, adds pyrosphere fire lid on the housing, and And installs chimney (15).

3, use type coal stove continuously according to claim 1 or 2 described reversibles, it is characterized in that, burner hearth when this cooking stove uses the square moulded coal (2) is rectangle, and And row discharging several piece coal is provided with (8) two of air-through bridges, makes between two thoraxes to communicate.
