Description

Hot-water boiler using solid fuel

The present invention relates to a hot water boiler using solid fuels such as coal, coke, and coal briquettes, and more particularly, to a coil-type heat pipe structure, an automatic ashtray, a combustion chamber cooling structure for self-heating water, and automatic discharge of residual combustion gas. By providing a hot water boiler including a cover structure and the like, the present invention relates to a hot water boiler using a solid fuel that can obtain high thermal efficiency, extend the life of the boiler, and can safely and easily manage and handle.

In general, a boiler is a means for heating a water tank circulated for hot water and heating while the burner is operated by a control system such as an electric ignition method, and the fuel mainly uses oil or gas.

In the case of boilers using oil or gas as fuel, the burden of using boilers is increasing in rural areas where income levels are difficult because maintenance costs are high, such as excessive cost of purchasing fuel.

In view of these characteristics, it is a recent trend that a lot of boilers used as solid fuels such as coal, wood, and coal briquettes are spread in rural areas.

Most of the existing boilers using solid fuels have a disadvantage in that the loss of heat through the outer wall of the combustion chamber is large because the boiler simply burns the fuel in the lower part of the hot water tank. There is a difficulty in management and handling such that the ash remains as it is before a person takes care of the remaining ashes, which causes the pores of the fire to be clogged, causing the fire to be easily extinguished. In particular, the metal parts around the combustion chamber Due to exposure to high temperatures, the overall life of the boiler is shortened, such as being easily corroded.

Therefore, the present invention has been devised in view of such a point, and the heat transfer tube installed inside the hot water chamber is configured in the form of a coil to obtain a sufficient heat transfer area, thereby minimizing heat loss, thereby obtaining high thermal efficiency, and lowering the combustion chamber. By installing a motor-driven automatic ashtray, it is possible to periodically shake off only the ash in time when the boiler is running, so that the fuel can be supplied smoothly and the fire is blocked to prevent the fire from extinguishing. The ash discharged after operation can be easily handled. In particular, a cooling means is provided in a member such as a heat transfer tube exposed to a high temperature combustion chamber to maintain its function even when exposed to high temperature for a long time. By automatically venting the remaining combustion gas inside the boiler The object of the present invention is to provide a hot water boiler using solid fuel that can cope with aggressively.
