Description

The solid fuel of hot blast heater

The present invention relates to a warm air fan, and more particularly, by making warm air using solid fuels such as low-cost coal, lignite, lump coal, shell coal, wood, etc. The present invention relates to a heat exchanger for solid fuel that supplies a clean and clean hot air.

In general, heating generates steam, hot water, or warm air with a boiler or a hot blast furnace (溫 風 爐) to distribute / supply through a pipe or a duct to warm indoor air. The heating is provided with a heat sink in the room, and the steam or hot water is circulated therein to directly warm the air in the room, or supply the warm air to the room to maintain the room temperature at the set value. At this time, the heating using hot air is applied to various fields such as theatres, offices, schools, as well as farms such as poultry farms, barns, and flower gardens because heating is efficiently performed evenly even though the heating area is large.

Conventionally, a hot air fan is an indirect heating type hot air fan that supplies warm air to a radiator heated by combustion and electric heat of fuels such as oil and gas, and high temperature combustion heat generated by burning fuel injected at high pressure. It is divided into direct heating type warm air heater which is supplied by And the air warmed by the warm air is circulated by natural convection, or by using a blower to keep the room warm by forced circulation.

At this time, the direct heating type hot air heater is preferred by farms such as poultry farms, barns, and flower gardens because the heating efficiency is better than the indirect heating type hot air fans by directly supplying combustion heat and fuel cost is reduced. However, the warm air using the heat of combustion contains a large amount of harmful substances such as soot, dust, combustion gas, etc. generated due to unburned fuel, which leads to serious problems that reduce the growth and development of livestock or crops, as well as the quality and marketability.

In addition, in order to reduce fuel costs as the production cost and management cost increase due to the rapid increase in the cost of heating in winter due to the continuous increase in oil price after the oil fluctuation, in some industries, solid such as coal, lignite, lump coal, shell coal, wood, etc. Fuel stoves are installed and heated. However, due to the nature of solid fuel stoves, the heating range is narrow and many stoves must be arranged, and as a result, they are used in relatively small offices, shops and farmhouses due to the hassle of re-collection after fuel supply and combustion. As it is practically impossible to use in a vast heating space such as a poultry farm, a barn house, a flower garden, etc., it is not possible to use the heating fan using oil, gas, and electricity.

Accordingly, the present invention has been devised in view of the above, and more specifically, by making hot air using solid fuels such as low-cost coal, lignite, lump coal, shell coal, wood, etc. In addition, the object of the present invention is to provide a heat exchanger for solid fuel that supplies a clean and clean hot air by a heating method by radiant heat.
