Warm air furnace having automatic residue discharge function

Abstract

The invention discloses a warm air furnace having an automatic residue discharge function. The warm air furnace comprises 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; a combustion chamber and an ash chamber are formed in the furnace body; the ash chamber is located below the combustion chamber; a baffle with a spring is arranged between the combustion chamber and the ash chamber; metal meshes are arranged in the combustion chamber; one end of each metal mesh stretches out of the furnace body; springs are arranged at the other ends of the metal meshes; and the controller is located on the furnace body and is connected with a sensor and a control motor of the feeding mechanism. The warm air furnace has the beneficial effects that the metal meshes are arranged in the combustion chamber, and biomass fuel undergoes stratified combustion due to the metal meshes and is combusted more fully, so that the heat production efficiency of the biomass fuel is improved; and the spring and the sensor are arranged on the baffle between the combustion chamber and the ash chamber, and when a certain amount of residues is accumulated on the baffle, the baffle is opened automatically, so that the baffle is more convenient than 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...

AI Technical Summary

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.
