The present invention relates to a dual structure boiler. More specifically, the present invention relates to a boiler that burns coal and has a structure in which a furnace and a water tank are separated.

In general, a conventional boiler has a furnace that burns fuel to generate heat and a water tank that warms water by the generated heat. In such conventional boilers, since combustion and heat collection of fuel are made in a limited space inside the same boiler, combustion is interrupted by the gas produced by combustion, thus limiting the maximum temperature obtainable by combustion. .

In addition, since the combustion is not performed at a high temperature, the fuel is not completely burned, and many harmful gases are generated due to incomplete combustion. In addition, since the combustion is not possible at a high temperature, the efficiency of the boiler to heat the water by the generated heat is not good.

Furthermore, it is inconvenient to treat dust and ash produced during the combustion of fuels such as coal.

Therefore, the present invention separates the space for generating heat by burning fuel, that is, carbon, and the space for warming water with the generated heat, so that the furnace can generate higher heat than a conventional boiler by the complete combustion of fuel. The aim is to provide a boiler which makes it possible to obtain heat more efficiently.

Moreover, this invention aims at making ash processing easy.
