Description

A boiler of firewood and lignite}

The present invention relates to a firewood and lignite boiler that can obtain heating, hot water and hot air. More specifically, the firewood and lignite are used as the main fuels. The present invention relates to a firewood and lignite boiler which can obtain a long time use of necessary heat.

In general, the boiler is to heat the water using a heat source such as oil or gas, so as to obtain the heating water required for heating the room, or hot water used in the bathroom, industrial or the like.

Therefore, such a boiler directly heats the water, and when the water is heated to a constant temperature, it is forced to circulate to the room or each necessary place by using a circulation pump to heat the room or store hot water in a separate hot water tank to store the required amount. As many times as used.

However, in such a boiler, when the temperature of the heated water drops below a certain temperature, the burner is ignited and the water is heated, and when the temperature is above a certain temperature, the circulating pump is operated to heat the heating, and thus a large number of ignition and extinguishing occurs according to the temperature change. There was a lot of fuel consumption and heat loss, the heat that is heated by direct heating is not all the heat exchange is made of hot water, there is a problem that the heat efficiency is low because the amount of heat lost to the outside of the boiler.

In addition, since the structure of the boiler is determined by the manufacturer according to the fuel used mostly as a boiler mainly using oil such as petroleum, there is a problem that the economic burden on heating or boiler maintenance costs is further increased by using expensive oil. .

Therefore, in order to solve this problem, cheap boilers using lignite and wood are being developed.

The present invention was devised to solve the above-mentioned problems. Using firewood and lignite as fuel, it is possible to obtain heating, hot water and warm air necessary for a long time with low cost and small amount of fuel input without incurring oil cost. It is to provide a firewood and lignite boiler in which the heat burned by burning in two fireboxes is stored in the heat medium oil, and the heat transferred to the heat medium oil with limited fuel is transferred to the secondary heating water so that the necessary heat can be used for a long time.
