Multifunctional direct-combustion and reverse-combustion heating furnace

Abstract

The invention discloses a multifunctional direct-combustion and reverse-combustion heating furnace comprising a furnace body; the furnace body is internally provided with an internal furnace which is provided and an upper opening and a lower opening; the internal furnace is internally provided with a combustion chamber; a reverse-combustion chamber is arranged between the furnace body and the internal furnace; the top of the internal furnace is provided with a mixed gas regulating device; the internal furnace located below the mixed gas regulating device is internally provided with a direct-combustion and reverse-combustion switching device; an upper sealing cover is mounted between the internal furnace located above the mixed gas regulating device and the furnace body; the top end of the furnace body is provided with an upper furnace cover; a smoke outlet communicating with the upper opening of the internal furnace is formed in the furnace body located above the upper sealing cover; the internal furnace located below the direct-combustion and reverse-combustion switching device is provided with an air sucking and filling device; the bottom end of the internal furnace is provided with an ash grating; the bottom end of the furnace body is provided with an air inlet and ash outlet device; the heating furnace has two working states including direct combustion and reverse combustion under the regulation of the direct-combustion and reverse-combustion switching device, and the heating furnace is suitable for cooking and heating water and has concentrated fire during direct combustion; and the heating furnace is suitable for heating and is high in heating speed during reverse combustion.

Description

technical field [0001] The invention relates to a furnace, in particular to a furnace capable of switching between direct firing and reverse firing states. Background technique [0002] In the north of our country, the temperature is low in winter and heating is required. In rural areas, heating furnaces are generally used for direct heating. In cities, heating furnaces are generally used to burn coal to heat the water in radiators or floor heating pipes, and rely on hot water circulation to achieve heating. [0003] When coal burns in the inner furnace of the heating furnace, many coal powder particles are too late to burn, and are taken away by the airflow and discharged into the air, which not only pollutes the environment, but also causes energy waste; during the combustion process of coal, there will be insufficient combustion. Toxic and combustible gases such as carbon monoxide are produced, and these gases are discharged into the environment, which not only causes ser...

Problems solved by technology

[0003] When coal burns in the inner furnace of the heating furnace, many coal powder particles are too late to burn, and are taken away by the airflow and discharged into the air, which not only pollutes the environment, but also causes energy waste; during the combustion process of coal, there will be insufficient combustion. Produces toxic and combustible gases such as carbon monoxide, which are discharged into the environment, not only causing serious air pollution, but also wasting energy

[0004] The heating furnace in the prior art has problems such as slow temperature rise and inconvenient cooking and boiling water.
