Energy-efficient heat supply furnace

Abstract

Provided is an energy-efficient heat supply furnace. A cooking range opening and a chimney connecting opening are arranged in the top of a furnace body. A furnace bottom is arranged on the lower portion of the furnace body, and a hearth is arranged on the upper portion of the furnace bottom. The upper portion of the hearth horizontally penetrates through the peripheral wall of the furnace body and is provided with a plurality of water heating tubes, and the water heating tubes are provided with ash sweeping plates in a covering mode. The hearth is a hollow sealed water tank and is provided with a main fire outlet and hole-shaped fire outlets. A fire collecting tube can be arranged on the main fire outlet in a covering mode, fire covering plates can be arranged on the hole-shaped fire outlets in a covering mode, and ash cleaning openings are formed in the peripheral wall of the furnace body. The energy-efficient heat supply furnace has the advantages that the water heating tubes can be used for enabling absorbed heat to be used for heating a room and sleeping; the ash sweeping plates can be used for cleaning ash on the water heating tubes, the thermal efficiency is improved, the fire collecting tube, a main fire covering plate and the fire covering plates are matched with one another, the heat power of the main fire outlet and the heat power of the hole-shaped fire outlets can be adjusted, and the heat utilization rate can be improved by more than 30%; the hollow sealed water tank, a chimney water tank in a chimney, a serial port water tank and the like are matched with one another, so that fuel is burned very completely, produced waste gas and waste slug are obviously reduced, and the purposes of going green, environmental protection, safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, and in particular relates to a high-efficiency and energy-saving heating furnace. Background technique [0002] In the prior art, most of the heating furnaces are basically made by connecting the furnace body to the chimney, or adding a furnace water tank on the outer layer of the furnace, and adding some flue water tanks and string water tanks inside the chimney. Make full use of heat energy to make it play a thermal effect. The heating stove made in this way is low in cost, cheap in price, easy to operate and practical, and is very popular among people, especially rural people. But such heating stoves are not quite suitable for the environmental protection and energy-saving environment advocated by today's society, and have the following defects: the main fire outlet on their burners is too large, so that the flame is drawn by the negative pressure of the flue. Walking, resulting i...

But such heating stoves are not quite suitable for the environmental protection and energy-saving environment advocated by today's society, and have the following defects: the main fire outlet on their burners is too large, so that the flame is drawn by the negative pressure of the flue. walking, resulting in a low heat utilization rate and wasting a lot of fuel; the fuel used cannot be fully burned, resulting in a large amount of waste gas and waste residue, which may pollute the air and cause inconvenience to people's lives, and may cause poisoning or even death to the user
