Abstract

The utility model provides a water vaporization furnace bridge, and provides a furnace bridge which has the advantages of being simple in technology, convenient in manufacture and generally suitable for various firewood-fire coal cooking ranges. The water vaporization furnace bridge is characterized in that a plurality of side-by-side small metal tubes are welded on a large sealed metal tube which bends into a U shape, and each small metal tube is communicated with the large metal tube through small holes; and the small metal tubes are provided with upward steam outlet small holes, a water inlet pipe is communicated with the furnace bridge, and the water inlet pipe is provided with a control valve. After a cooking range is ignited, high temperature water steam can automatically jet onto fervent coal in a burning furnace so as to generate a chemical reaction to support combustion, and enable the burning of fuel to be more fully.

Description

The water vapor grate

Technical field

The utility model relates to stove and accessory and makes the field, is a kind of grate that fires the bavin coal-fired stove, particularly a kind of water vapor grate.

Background technology

At present, the cooking stove of vast rural area family expenses all is built into brick clay, and ventilation condition is poor, over-emitting black exhaust when coal combustion or faggot, and severe contamination atmosphere, the thermal efficiency are extremely low.It is combustion-supporting that water vapour is ejected in the burner vaporization; Be that a kind of full combustion of fuel that makes improves very effective method of stove thermal efficiency, for example the patent No. is that the ZL01256690.X " new moulded coal bavin energy-saving gasification stove " and the patent No. are technology such as ZL02133497.8 " water gas type fuel-saving stove without smoke ".But because manufacturing technology is complicated, cost is high, and steam produces the slow and pressure of speed factor such as can not control, and technology and product are failed fine popularizing.

Summary of the invention

The utility model provides a kind of technology simple; Easy to make, can water-vapour spray vaporization in the burner is combustion-supporting, and steam to produce speed fast; Steam pressure and firepower are adjustable; Thereby improve the utilization ratio of fuel, reduce discharge of harmful gases, generally be applicable to the water vapor grate of various combustion bavin coal-fired stoves.

The technical scheme that the utility model adopted is: the several little metal tubes side by side of welding on the big metal tube of the sealing that curves U-shaped; There is aperture to be connected between the little metal tube of each root and the big metal tube; Have small steam outlet upwards on the little metal tube, have a water inlet pipe to be connected, control valve is housed on the water inlet pipe with grate; It is characterized in that grate is a hollow, have aperture upwards on the grate.

The beneficial effect of the utility model is: can be under field conditions (factors), can high-temperature vapor be ejected into automatically that chemical reaction takes place on the coal red-hot in the burner is combustion-supporting, and flow of steam at high temperature drives grate below air again and upwards flows; Greatly improve the ventilation condition of cooking stove; Make fuel combustion more abundant, and steam generation speed is fast, steam pressure and firepower are adjustable; Thereby improve the utilization ratio of fuel, reduce discharge of harmful gases.This technology and product are very easily popularized, and generally are applicable to various combustion bavin coal-fired stoves, will play important impetus to China's energy-saving and emission-reduction and protection environment.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the general structure cross-sectional schematic of the utility model.

Among Fig. 1: the big metal tube of 1.U shape, 2. little metal tube, 3. little vapor opening, 4. water inlet pipe, 5. control valve.

The specific embodiment

In Fig. 1; Go up the several little metal tubes (2) side by side of welding at the big metal tube of the sealing that curves U-shaped (1); There is aperture to be connected between the little metal tube of each root and the big metal tube; Have small steam outlet (3) upwards on the little metal tube (2), have a water inlet pipe (4) to be connected, control valve (5) is housed on the water inlet pipe with grate.

A few minutes after cooking stove is lighted, treating has a small amount of carbon deposit on the grate, and little metal tube temperature reaches more than the 100; Open the water inlet pipe control valve, inject the big metal tube of running water to U-shaped, again closed control valve; Grate can be ejected into high-temperature vapor on the coal red-hot in the burner that chemical reaction takes place is combustion-supporting automatically, and flow of steam at high temperature drives grate below air again and upwards flows, and greatly improves the ventilation condition of cooking stove; Make fuel combustion more abundant; And steam generation speed is fast, thereby improves the utilization ratio of fuel, reduces discharge of harmful gases.The big I of steam pressure and firepower is as required through injecting how much regulating and control of the grate water yield.

In order to guarantee the steam vaporization rate; Can as required grate be made all size; Metallic sheath can be made with above copper tube or aluminium-alloy pipe or stainless steel tube, the size about the aperture that is connected between little metal tube and the big metal tube will be made, and the steam venthole is littler.

Claims

1. water vapor grate; There is aperture to be connected between the several little metal tubes side by side of welding on the big metal tube of the sealing that curves U-shaped, the little metal tube of each root and big metal tube, has the small steam outlet that makes progress on the little metal tube; There is a water inlet pipe to be connected with grate; Control valve is housed on the water inlet pipe, it is characterized in that grate is a hollow, have aperture upwards on the grate.
