Warm air furnace having automatic residue discharge function

Abstract

The invention provides a warm air stove with an automatic slagging function, which includes a furnace body, a storage bin, a feeding mechanism, a heat exchange chamber, a water jacket, a water pipe, an air pipe, a flue, an oxygen supply mechanism and a controller. The furnace body is provided with a combustion chamber and an ash chamber, the ash chamber is located below the combustion chamber, a baffle plate with a spring is provided between the combustion chamber and the ash chamber, a metal mesh is arranged in the combustion chamber, and the metal mesh One end of the net extends out of the furnace body, and the other end is provided with a spring. The controller is located on the furnace body and is connected with the sensor and the control motor of the feeding mechanism. The beneficial effects of the present invention are as follows: a metal mesh is installed in the combustion chamber, the metal mesh makes the biomass fuel burn in layers, the biomass fuel burns more fully, and improves the heat production efficiency of the biomass fuel; A spring and a sensor are installed on the baffle, and when a certain amount of residue is accumulated on the baffle, it will be opened automatically, which is more convenient than using a grate.

Description

technical field [0001] The invention belongs to the field of heating equipment, in particular to an air heater with automatic slag discharge function. Background technique [0002] At present, most cities in my country have carried out a large-scale ban on coal-fired boilers, especially coal-fired steam boilers that pollute the environment seriously. Therefore, people continue to develop new energy sources. Biomass briquette fuel is a low-carbon and environmentally friendly clean energy source. It can achieve zero carbon dioxide emissions during combustion, and its sulfur content is only about 20% of that of coal. It has high nutrient content, is easy to ignite, has a higher combustion rate than coal, has low production costs, and has a wide distribution of resources. It is the only new energy resource that stores solar energy in a chemical state among new energy sources. At present, the heating, drying, and heating equipment used by most enterprises and institutions are pr...

Problems solved by technology

At present, the heating, drying, and heating equipment used by most enterprises and institutions are provided by steam and hot water boilers, and then converted through multiple methods, which increases the heat exchange program, increases the investment in supporting facilities, and increases the operating cost.

In the existing heaters, because the biomass fuel burned is solid and contains more non-combustible substances, it is easy to cause insufficient combustion; it is also because of these non-combustible substances that it is easy to form more residues, and it is difficult to pass through the grate. It also makes feeding more difficult and often requires manual operation.
