Abstract

The utility model relates to a smokeless, energy-saving, heating and cooking multipurpose stove, which belongs to the technical field of civilian solid fuel stoves. The technical problem to be solved is to provide a smokeless, energy-saving, multi-purpose heating and cooking stove with sufficient combustion and obvious energy-saving effect. The technical solution is that the composition includes a furnace body, a furnace bar, a water jacket, an insulation layer and a furnace tank. The water jacket is placed inside the insulation layer, and a secondary air chamber surrounding the furnace tank is arranged between the water jacket and the furnace tank. The air inlet of the chamber is located at the lower side of the furnace body, and the air outlet of the secondary air chamber is a plurality of small air outlets spaced around the furnace mouth. The water jacket is set inside the insulation layer, and there is a ring-shaped secondary air chamber between the water jacket and the furnace tank, so that the water jacket and the secondary air intake can fully absorb the radiant heat around the furnace tank, so that the water in the water jacket heats up quickly. The temperature of the secondary air is high, which is good for combustion. The coal is incompletely burned in the furnace tank, and the generated flue gas is mixed with the secondary hot air above the furnace mouth and completely burned, so it realizes smoke-free, energy-saving and high thermal efficiency. It is especially suitable for family heating, cooking and bathing.

Description

Smoke-less power-saving heating-cooking multipurpose furnace

Technical field

The utility model relates to a kind of smoke-less power-saving heating-cooking multipurpose furnace, belongs to civilian solid fuel cooker technical field.

Background technology

In the ZL98252045 technology, a kind of civil heating stove is disclosed, its objective is provides a kind of assurance heating stove to ventilate, and fired coal combustion is complete, the civil heating stove that high heat is imitated, economized on coal.Its formation is that symmetrically arranged two secondary wind inleting tubes are arranged in the body of heater, and secondary wind inleting tube is placed through in the heat-insulation layer of body of heater, and the water jacket ring places outside the burner hearth heat-insulation layer.Its advantage is, compares with traditional coal furnace, and it is combustion-supporting that being provided with of secondary wind is beneficial to, and being provided with of water jacket is beneficial to the heat loss that reduces the body of heater appearance.Its weak point is, be located at secondary wind inleting tube in the insulating layer of furnace body and make and pass the pre-thermo-lag of secondary wind in it, and its cross section is too small, and combustion-supporting effect is poor, and effect of coal saving is not obvious.In addition, because its water jacket ring places outside the burner hearth heat-insulation layer, can make that the water temperature in the water jacket rises slowly, during use, the low excessively phenomenon of water temperature can occur, this can use to the user and bring inconvenience.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of sufficient combustion, and the tangible smoke-less power-saving heating-cooking of energy-saving effect multipurpose furnace overcomes above-mentioned shortcoming of the prior art.

It is as follows to solve the problems of the technologies described above the technical scheme that is adopted:

A kind of smoke-less power-saving heating-cooking multipurpose furnace, it comprises body of heater, fire bars, water jacket, heat-insulation layer and retort, said water jacket places the heat-insulation layer inboard, be provided with secondary air chamber between water jacket and retort around retort, the air inlet of secondary air chamber is located at the side lower part of body of heater, and the air outlet of secondary air chamber is a plurality of little air port around the fire door circumferential interval.

For making full use of the waste heat in the flue gas, above-mentioned smoke-less power-saving heating-cooking multipurpose furnace, said upper of furnace body is provided with flue, the annular smoke flue border is provided with additional water jacket, additional water jacket lower end is communicated with water jacket, and the additional water set upper side is provided with delivery port, and the water jacket lower end is provided with water return outlet.

For effectively utilizing the heat loss of fire door, above-mentioned smoke-less power-saving heating-cooking multipurpose furnace, said fire door top is provided with covers the formula small water sleeve, and small water sleeve is provided with water return outlet, is that flexible pipe, threeway are connected between the delivery port of small water sleeve and the delivery port of additional water jacket.

For the benefit of keep environment clean and tidy, above-mentioned smoke-less power-saving heating-cooking multipurpose furnace, said body of heater is the circular upper part and square lower part structure, the fire bars bottom is provided with storage slag drawer.

Smoke-less power-saving heating-cooking multipurpose furnace provided by the utility model, its water jacket is located at the heat-insulation layer inboard, and be provided with annular secondary air chamber between water jacket and retort, can make water jacket and secondary air fully absorb retort radiant heat all around like this, make the water temperature in the water jacket rise fast, secondary air temperature degree height, favourable combustion-supporting.Coal-fired in retort imperfect combustion, the flue gas of generation more than fire door with secondary hot-air mixings completing combustion, smokeless, energy-conservation, high heat effect that historical facts or anecdotes has showed.The utility model is specially adapted to domestic heating, cooking and bathing etc.
