All coal-fired stoves from history are expected to be kept from the stove core. It can be seen that the stove core belongs to the core part in the stove, and no stove core is available, so that no perfect stove exists. The most of the fuels used by the stove are wood and coal, the wood used as the fuel has large smoke and much dust, most of the fuels used as the fuel are coal for heating, the coal combustion temperature can melt steel, and even if a small amount of coal is used as the fuel for heating, the stove barrel and the stove surface are easy to burn and deform, so all the stoves using the coal for heating must use the stove core.

Most of the furnace cores on the market are made by stirring common crushed stone powder and cement, and the furnace core has the defects that the furnace core wall is easy to burst under the action of high temperature, the service life of the furnace core is one to three years, the service life of the furnace core made of the fire clay is only a little better than that of the furnace core made of the sand stone cement, and the manufacturing of the furnace core with high temperature resistance and long service life becomes a technical problem to be overcome by furnace manufacturers.

The old type furnace core is not environment-friendly and is gradually eliminated due to coal consumption, the old type furnace core is developed to the present, the south white energy-saving furnace core and the expensive gasification furnace core which are relatively acceptable are developed, the furnace core for the south white energy-saving furnace core is used, but smoke exists, the smoke and water flow reducing effect is not a result which is wanted by people, the south white furnace core is short in service life, the furnace core can be changed for two years only in winter generally, the shortcoming is obvious, the expensive gasification furnace core has the gasification function, but ash needs to be filled around the furnace core, flame does not have impulsive force in use, the reason is that a supply system does not circulate, the service life is only one to three years, and the common shortcoming of the south white furnace core and the expensive gasification furnace core is short in service life and not environment-friendly.
