Description

Boiler that have multiple water tube and heat exchanger}

The present invention is provided with a hot water tank having a multi-layered configuration to enable individual heating respectively, and the flue is configured so that one or more heat sources to the hot water tank of the multi-layered configuration can be effectively applied to the hot water tank and the firebox for supplying the main heat source. Thus, the complete combustion rate of the firebox is high, rapid individual heating by rapid hot water heating is possible, and heat loss caused by waste heat can be prevented to improve energy efficiency, and also pass the flue outside the boiler body. The present invention relates to a boiler having an individual heating double layer hot water tank and a multi-tubular heat exchanger, which is configured to allow the use of the heating device of the fireplace, as well as the removal of the burning and dust in the flue.

 In general, the boiler is to supply the heating or hot water by using the heated hot water or steam generated by heating the water in the hot water tank through the heat source obtained by burning the fuel, the hot water tank for storing water in the drum shape, and the heat Boiler main body to heat water by heat-exchanging flue supply, firebox (combustion chamber) to generate heat source to heat water by burning fuel, and other feed, drain and flue that supply and discharge water to hot water tank. It consists of intake and exhaust part that discharges waste heat to the outside of boiler body, fuel supply part that supplies fuel used for combustion and other accessories.

These boilers can be divided into boilers using solid fuel, liquid fuel, and gaseous fuel, depending on the fuel used for combustion to generate heat source. Solid fuel boilers and liquid fuel boilers are used for treating ash generated after combustion and fuel. Due to the difficulty of storage and handling, the use is gradually decreasing, and in the high oil price era, the operation cost of the liquid fuel boiler acts as a big burden, so the fuel is very convenient and the gas is relatively inexpensive. Although it is being replaced by a fuel boiler, in the case of a gas fuel boiler using gas, it is difficult to completely burn the fuel, and thus the combustion efficiency is lowered. It was difficult to obtain sufficient heating efficiency.

In this situation, the development of technology to improve the heating performance of the boiler and to obtain high energy efficiency has been actively progressed. In particular, as a core technology of the boiler, the structure of the heat exchanger to heat the hot water tank inside the main body to heat it A number of techniques have been published in the literature to improve some of these problems.
