COMBUSTION APPARATUS

A combustion device is provided to prevent environmental contamination and create new energy source by storing utility gas. A combustion device comprises a combustion chamber(10), a condensation removing unit(30), and a utility gas storage unit(40). In the combustion chamber, a fuel supply pipe(4), a steam supply pipe(20), and an exhaust pipe(8) are connected. The fuel supply pipe supplies CaCO3 powder and coal powder to the fuel. The steam supply pipe supplies the steam of the high temperature. The exhaust pipe ejects the exhaust gas due to burning coal powder, the steam of high temperature, and the CaCO3 powder at the same time. The exhaust pipe is connected to a chimney(6). The condensation removing unit condenses and removes pollution element of the exhaust gas within the exhaust pipe. The condensation removing unit is installed within the exhaust pipe. The utility gas storage unit is installed to store utility gas in which the condensation is removed.
