Description

Double-flue direct-fired heating furnace

technical field

The utility model relates to a heating furnace, in particular to a double-flue direct-fired heating furnace.

Background technique

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, also known as the heat sink, releases the heat in the hot water into the room to increase the indoor temperature. The water flowing out of the heat sink has cooled down significantly and then flows back into the water tank to start a new cycle of heating → heat dissipation .

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 most of the improvements to traditional heating furnaces are limited to enlarging the hearth space of the furnace to increase the amount of coal burned. Although such an improvement can meet the demand for increasing the heating area, there are still the following disadvantages:

The chimney of the stove is a cannon that extends directly to the outside, releasing a large amount of heat to the outside and running away in vain. The utilization rate of heat is low and a lot of coal resources are wasted;
