Description

A boiler using lump coal and petroleum oil}

The present invention relates to a boiler that can combine lump coal and oil as fuel, and more particularly, lump coal and oil that combines lump coal combustion chamber and oil combustion chamber into one combustion chamber so that lump coal and oil can be used as fuel at the same time. It is about a combined use boiler.

Boilers capable of supplying heating and hot water by combining oil and wood have already been known. As shown in Korean Patent Application No. 61337 of "Dongsung Heat Co., Ltd.", co-applicant of the present invention, "The hot water boiler combined with oil and wood," it is centered on mountainous or rural areas where combustion wood can be easily obtained in the high oil price era. In many cases, oil is used as a fuel when wood is burned during the day and long hours of heating are required at night.

The conventional boiler using oil and wood is installed separately from the oil combustion chamber and the wood combustion chamber, so the appearance of the boiler is too large, so that the installation area is not required and the boiler manufacturing cost and installation cost are high. In addition, there was an inconvenience and risk of manually igniting wood fuel, and there was a significant inconvenience due to the manual conversion between wood or oil fuel. In addition, it was very inconvenient because people had to clean the accumulated ashes directly after burning wood, and there was a problem that the association was easily blocked due to the sludge generated by using wood fuel, and the heat transfer of the boiler due to the sludge. It is true that there has been a disadvantage in that the effect is reduced.

Therefore, in the patent application of Dongsung Heat Co., the co-applicant of the present invention, the oil combustion chamber and the wood combustion chamber are integrated to burn oil and wood in one combustion chamber, and the wood charged in the combustion chamber is automatically ignited by a burner. The combination of oil and wood prevents the user from having to clean the combustion chamber and prevents the blockage or sludge from depositing in the combustion chamber by discharging the ash generated by burning wood through the fan attached to the burner. Hot water boiler was proposed.

However, in the proposed oil and wood combined hot water boiler, when a fan for discharging ash generated when burning wood is driven, a serious problem of dust is generated, and there is a need for improvement. There was a problem. This can be said to be one of several problems that arise from the use of wood.

The technical problem to be achieved in the present invention is to provide a boiler that can be used in combination with coal and oil. In addition, by supplying an automated device that can change the type of fuel depending on the situation when burning coal and oil in the combustion chamber, it solves the problems of the existing wood and oil boiler and at the same time, it is more powerful than the existing design. It is to be able to build a boiler that occurs.

Accordingly, an object of the present invention, in the boiler that can be used for both oil and lump coal, the boiler fire chamber 20 is provided in the boiler body 10 and the flue (60) for discharging the waste gas generated in the fire chamber to the outside (60) ) And a cleaning tool 30 for discharging the sludge of the burnt lumps to the outside, a handle 200, and a combustion chamber 50, and are provided with an automatic control controller 90 to automatically switch fuel. It is to provide a combined coal oil boiler.

In addition, the boiler is characterized in that the fuel stored in the lump coal and the oil stored in the external oil storage tank charged in the boiler firebox 20 as a fuel.

In addition, the fire chamber is characterized in that the coal combustion chamber and the oil combustion chamber is integrated into one combustion chamber is manufactured.

Hereinafter, with reference to the accompanying drawings will be described in detail.

1 is a plan view of a lump coal oil combined use boiler of the present invention. As shown in the figure, the outside of the boiler fuselage 10, the cleaning tool 30, the combustion chamber 50, the combustion chamber cleaning port 40 and the flue 60 is attached.

2 is a front view of the lump coal oil combined use boiler of the present invention. As shown in the figure, the firebox 20 is provided inside the boiler fuselage 10, and the firebox lid is provided at the top to block the boiler firebox 20 from the outside. In addition, the combustion chamber 50 and the combustion chamber cleaning holes 40 are formed above the flue 60 so that the combustion chamber can be easily cleaned to improve thermal efficiency. The cleaning tool 30 is attached to the backing handle 70 and the backing support 80, and the cleaning of the backing tool becomes easier due to the lever of the backing handle.
