Heating furnace

Abstract

The invention discloses a heating furnace, and belongs to heating equipment. The heating furnace comprises a furnace body, a hearth surrounded by a furnace wall, a feed port, a fire grate, a slag discharge chamber, an upper furnace ring and a box body; the box body includes an outer-layer box body and an inner-layer box body; a sandwich layer is arranged between the outer-layer box body and the inner-layer box body; a smoke outlet and a hot water outlet pipe are arranged at the top of the box body; a water return pipe is arranged at the lower part of the furnace body; a water return channel and a smoke outlet channel are arranged in the furnace body; the water return pipe is communicated with the sandwich layer through the water return channel; the smoke outlet channel is respectively communicated with the hearth and an inner cavity of the inner-layer box body; a smoke stop device is arranged in the inner cavity of the inner-layer box body of the box body, and includes a transverse baffle plate and a vertical baffle plate; the inner cavity of the inner-layer box body is divided into a left cavity and a right cavity; multiple inclined hot water circulating pipes are staggered in the left cavity and the right cavity; and each inclined hot water circulating pipe is communicated with the sandwich layer. The heating furnace has such characteristics as improvement of the heat utilization rate and saving of the coal resource.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating furnace. Background technique [0002] Due to the cold winter in the areas north of the Yangtze River in my country, artificial heating is required indoors to keep out the cold. Generally, large-scale boilers are used for municipal unified heating in cities, but municipal unified heating is generally not implemented in areas along the Yangtze River, rural areas, and townships. Or the indoor unit can set the indoor heating equipment for heating by itself. At present, the most commonly used household / indoor heating equipment among the people is still a coal-fired heating furnace. The existing coal-fired heating furnace uses coal to provide heat to heat the hot water in the water tank, and then provides the hot water to the indoor heating piping system. The indoor heating piping system refers to the water pipes installed indoors and their connections for heat dissipation. The radiator, ...

Problems solved by technology

[0003] Although the traditional coal-fired heating furnace has a long history of use, with the improvement of people's living environment and quality of life, it is gradually difficult to meet the heating needs of people with larger living spaces in terms of coal-burning efficiency and indoor temperature. And the current improvements to traditional heating furnaces are mostly limited to increasing the furnace space of the furnace to increase the amount of coal burned

Although such an improvement can meet the needs of increasing the heating area, there are still the following disadvantages: the heat utilization rate is low, and a large amount of coal resources are wasted
