BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a furnace tubular water boiler, which is to include an internal body having a combustion chamber and a heat transfer chamber and a plurality of the internal bodies. It has a constitutional feature including an outer body formed integrally to have a predetermined space portion with the inner body by the protruding support rod of the, the water is made to enter and exit the space portion to enable faster heat exchange during boiler operation It relates to a furnace tubular boiler.

As is well known, as a heating principle by a boiler, heating water is passed through a boiler, a heat exchanger, and a heating pipe by a circulation pump, and then circulated again to the boiler, and by a drain pump simultaneously operated with the circulation pump. By passing cold water through the heat exchanger and performing heat exchange with the heating water, it has an operating principle of providing a desired heating temperature and hot water for hot water supply.

1 is a schematic cross-sectional view of the boiler 1 to which the prior art is applied, and is provided with a circulation pump (not shown) by providing the heat transfer means 20 inside the water pipe 10. It is possible to achieve the inflow and outflow of water into the water pipe (10), and after heating the water introduced by the heat transfer means 20, and again through the heat exchanger (not shown) and the heating pipe By feeding back to the boiler, it had a configuration for realizing a desired heating temperature and providing hot water for hot water supply.

Referring to FIG. 1, a conventional boiler 1 includes a water pipe 10 having an inlet 12 and a drain 11 for making water in and out, and a burner inside the water pipe 10. A plurality of plumbing pipes 30 in which the ignition part of the 50 is hermetically coupled to the combustion pipe 30 and integrally communicate with the combustion pipe 30, and are concentrated on the space portion 40 of the water pipe 10. (20a, 20b, 20c), and the connection to the exhaust port 13 formed in the upper end surface of the water pipe 10, it was to have a configuration for discharging the combustion gas.

In more detail, the operation principle of the burner 50 generates a flame into the combustion pipe 30 and simultaneously generates a plurality of flames and combustion gases through the plurality of the associated pipes 20a, 20b, and 20c. Is introduced to be discharged to the exhaust port 13, the water introduced through the water inlet 12 of the water pipe 10 is heated to be discharged to the discharge port 13 through the heat exchanger, heating pipes and the like. It was to have an operating principle to circulate back to the boiler.

The above-described configuration is a type in which an associated pipe and a water pipe are mixed, and are the most widely used heat exchange system.

However, according to the above configuration, the heating efficiency can be maximized only when the diameter of the combustion pipe 30 and the heat transfer areas of the pipes 20a, 20b, and 20c are formed to have an inverse relationship with each other. In more detail, in order to realize the maximum heat transfer efficiency, more connections 20a, 20b, and 20c should be formed inside the water pipe 10, so that the diameter of the combustion pipe 30 is equal to the diameter of the pipe 20a and 20b. Since it is bound to be limited by the number and heat transfer area of (20c), the manufacturing process is very demanding, as well as problems such as maintenance is not easy.

In addition, when the boiler 1 is used for a long time, problems such as deterioration of heating efficiency are generated because non-combustible substances are constricted in the inner diameters of the pipes 20a, 20b, and 20c, and these can be effectively cleaned. Since there was no configuration, a structural problem has arisen in which the combustion pipe 30 and the associated pipes 20a, 20b, and 20c must be replaced as a whole.

The present invention is to solve the above-mentioned general problems, the inner body having a combustion chamber and the heat transfer chamber therein, the outer body containing the inner body therein, and the predetermined between the inner body and the outer body Since a plurality of protruding holding rods are formed to achieve the space portion of the space, water is introduced into the space portion, and an object of the present invention is to provide a furnace tubular boiler capable of providing a faster heating effect and providing hot water for hot water supply when the boiler is driven.
