Abstract

A high-efficiency gasification, energy-saving, and environment-friendly heating furnace is designed to solve the problems of insufficient fuel combustion and black smoke emission in existing heating furnaces. It includes a water-jacketed furnace body and a water-laden furnace cover, and is characterized in that: the upper part of the furnace of the water-jacketed furnace body is dome-shaped, and internal and external through holes are arranged on the dome-shaped furnace wall; and the water-jacketed furnace body A closed maintenance layer is set around the closed maintenance layer, wherein the bottom surface of the closed maintenance layer is provided with a through hole to the ash chamber; the closed maintenance layer is provided with a fan pipe interface. Since the utility model has a large amount of oxygen entering the furnace from the dome-shaped furnace wall and rising from the bottom of the furnace bar, there is sufficient oxygen in the furnace to support combustion, so the utility model is easy to ignite, heats up quickly, has a strong flame, and the fuel burns fully. , into ashes, and no smoke and dust, no environmental pollution, showing a significant energy-saving effect. It is suitable for use in various civil places such as families, units, and communities.

Description

Efficient gasification, energy saving and environmental protection heating furnace

Technical field: The utility model relates to a heating stove for civil use.

Technical background: This utility model is aimed at the improvement of the "high-efficiency energy-saving heating furnace" announced in ZL200420015791.7. Although the high-efficiency and energy-saving heating furnace has achieved obvious technical effects of improving thermal efficiency and saving energy through technical measures such as increasing the overall heat exchange area of the furnace and making full use of the flue gas heat. However, in use, the designer still found that the stove still needs to be improved, which mainly refers to how to make the fuel burn more fully, because the stove not only still emits black smoke when burning, but also does not burn the slag after burning. The heat is not completely burned off.

Utility model content:

The task of this utility model is to provide a high-efficiency gasification, energy-saving and environmental protection heating furnace for the practical problem that the existing technology cannot fully burn the fuel. reduced to ashes.

Its technical solutions include: a high-efficiency gasification, energy-saving and environmental protection heating furnace, including a water-jacketed furnace body and a water-encased furnace cover, which is characterized in that: the upper part of the furnace body of the furnace is arched, and the arched furnace The wall is provided with internal and external through holes; and a closed maintenance layer is provided around the water jacket furnace body, wherein the bottom of the closed maintenance layer is provided with a through hole to the ash chamber; the closed maintenance layer is provided with a fan pipe interface.

In addition, in order to facilitate the taking of the water ladle furnace cover and prolong the service life of the circulating water channel connecting the water ladle furnace cover and the furnace body, the circulating water channel connecting the water ladle furnace cover and the furnace body adopts a rigid sealed movable connection, that is, through The metal furnace cover can be installed to lift or close the water ladle furnace cover.

Compared with the prior art, since the utility model adopts a dome-shaped furnace with a through hole and a closed maintenance that can ventilate inward, when the fan blows inward, a large amount of oxygen will be released from the dome. The shaped furnace wall enters the top of the furnace, and at the same time, air rises into the furnace from the bottom of the furnace bars, so that there will be sufficient oxygen in the furnace to support combustion. Facts have proved that the main advantages of the utility model are: 1. easy to ignite and heat up quickly. Generally, rice can be cooked in 8 minutes after igniting, and the fire is urging people to keep busy. ②The flame is strong, and the flame is blue-green, like a blowtorch. When the furnace cover is lifted, people's eyes are burned and people dare not look at it for a long time. ③ No matter the quality of the coal is good or bad, it can be fully gasified and burned to ashes, and it is smoke-free, dust-free, and environmental-pollution-free. ④ The designer once conducted experiments in a large workshop that was poorly closed at the beginning of winter. The furnace with a diameter of 20cm was equipped with 108 carbon steel sheets for heating. It used 5.3kg of coal, 150kg of water, and ignited for 25 minutes. It was tested by electronic temperature control means. The temperature of the upper half of the chip is 70°C, and the return water temperature is 60°C, which shows its high thermal efficiency. ⑤ The utility model has remarkable energy-saving effect. In addition, since the circulating water channel connecting the water-laden furnace cover and the furnace body of the utility model adopts a rigid sealed movable connection, that is, the water-laden furnace cover can be lifted or covered by the metal furnace cover, so compared with the prior art, both It is easy to take and can prolong the service life of the circulating water channel connecting the water ladle furnace cover and the furnace body.

BRIEF DESCRIPTION OF THE DRAWINGS: Figure 1 is a schematic structural view of the utility model.

Specific embodiments: as shown in Figure 1, the high-efficiency gasification, energy-saving and environmental protection heating furnace provided by the utility model includes a water jacket furnace body and a water jacket furnace cover, and is characterized in that: the furnace upper part of the water jacket furnace body 3 is domed Arched 5, internal and external through holes 6 are provided on the arched furnace wall; and a closed maintenance layer 4 is provided around the water jacket furnace body 3, wherein the bottom surface of the closed maintenance layer 4 is provided with through holes 2 to Gray room; the closed maintenance layer 4 is provided with a fan pipe interface 10 . In addition, the water-laden furnace cover 7 of the heating furnace is connected to the furnace body by a rigid sealing movable connection, that is, the water-laden furnace cover 7 can be lifted or covered through the metal furnace cover part 8 . When the furnace is in use, when the amount of fire or water temperature meets the needs, the fan can be turned off, and the air intake of the furnace is controlled by the opening of the furnace door 1, so as to meet people's requirements for heating or cooking and water.

The utility model is suitable for use in various civil places such as families, units and communities.
