Description

Boiler combustion chamber with air cooling plate for boiler combustion chamber and the air cooling plate

The present invention relates to an air cooling plate for a boiler combustion chamber and a boiler combustion chamber having the same. More specifically, the air cooling plate for a boiler combustion chamber in which an air layer is formed between the inner wall of the combustion chamber and the heat insulating material can be easily disposed on the front surface thereof. And a boiler combustion chamber having the air cooling plate.

In general, a gas boiler burns fuel to heat the heating water using a heat exchanger, and circulates the heated heating water through a pipe installed in the room to heat the room.

In addition, the gas boiler generates heat by supplying gas introduced through the gas valve and the gas supply pipe to the gas burner, and the generated heat is transferred to the heat exchanger through the insulated combustion chamber to heat the heating water inside the heat exchanger. do.

On the other hand, in the conventional gas boiler combustion chamber in order to prevent the heat loss while blocking the high temperature flame and the outside of the combustion chamber, there is a case of applying an insulation or forming an air flow path between the insulation and the combustion chamber inner wall. And in order to maximize the thermal insulation effect, by supplying air to the air flow path to increase the thermal insulation performance.

However, in such a structure, a complicated additional structure must be provided in order to supply air into the air flow path. In addition, since some of the air normally supplied for gas combustion is used as the air supplied to the air flow path, there is a problem in that the combustion performance is deteriorated and the required blowing amount is large.

The present invention devised in view of the above-described circumstances is provided with an air cooling plate for a boiler combustion chamber and an air-cooling plate for allowing an air layer for thermal insulation to be formed in the combustion chamber with a simple structure, easy installation in the combustion chamber, and easy insulation. The purpose is to provide a conventional boiler combustion chamber.
