【発明の詳細な説明】
本発明はボイラーの燃焼装置に係わり、熱交換器におけ
る燃焼温度分布を向上せしめ、熱交換効率を高めるとと
もに、熱交換効率を高めるための熱拡散板の位置を変え
、耐久性の良い熱拡散板を得ることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a boiler combustion device, which improves combustion temperature distribution in a heat exchanger, increases heat exchange efficiency, and changes the position of a heat diffusion plate to increase heat exchange efficiency. The purpose is to obtain a durable heat diffusion plate.
従来、小型のガスおよび灯油ボイラーにおいては、燃焼

熱交換器の外壁に１通水管を密着し、この通水管は通水
しながら、燃焼バーナーの燃焼によって水を加熱し、高
温水を負荷狽Ｕに送水する。Conventionally, in small gas and kerosene boilers, there is a heat exchanger that surrounds the combustion burner, and a water pipe is tightly attached to the outer wall of the heat exchanger, and this water pipe is used to conduct combustion while passing water. The water is heated by combustion in the burner, and the high-temperature water is sent to the load chamber U.

および酸化腐蝕が激しく、耐久性が乏しく、そのために
、普通の耐熱耐蝕金属は使用不可能な状態となり、した

い欠点を有していた。During this combustion, a flat heat diffusion plate is installed in the combustion chamber above the combustion nozzle and surrounded by the lower end of the heat exchanger, and this heat diffusion plate spreads the combustion temperature to the outside of the heat exchanger. The idea is to improve the heat exchange efficiency by improving the temperature distribution.However, the quasi-diffusion plate force is located directly above the combustion burner in the combustion chamber, so the temperature of the heat diffusion plate itself increases. The temperature rises significantly, thermal deformation and oxidation corrosion are severe, and the durability is poor, making ordinary heat-resistant and corrosion-resistant metals unusable. It had drawbacks.
本発明は上記従来の欠点を解消するもので、以下にその
一実施例を図にもとづいて説明する。The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

This is a flat heat diffusion plate provided directly above the plate fins 6 which provide some resistance to the passage of the combustion exhaust gas and reduce the passage speed of the combustion exhaust gas.This heat diffusion plate 10
is the auxiliary exhaust pipe 11, the exhaust pipe 12, and the mounting piece "13".
is held by. 14 is a windbreak tube, 16 is a water storage tank, and has a water return port 16 returning from the load side and a water outlet 17 facing the pump 8 side. 18 is a make-up water inlet, 19 is an oil level regulator provided in the case of a kerosene boiler, 2o is an oil feed port, and 21 is an electrical equipment box.
上記構成において、バーナー′２で燃焼すると、吐出加
熱管６を主体に加熱し、燃焼排気ガスは対気流によって
プレートフィン６間を通って、上方に流通しようとする
が、熱拡散板１０が、この流。In the above configuration, when combustion occurs in the burner '2, the discharge heating pipe 6 is mainly heated, and the combustion exhaust gas tries to flow upward through the plate fins 6 by convection, but the heat diffusion plate 10 This style.

れるのである。Since the combustion gas in the combustion cylinder section is discharged from the exhaust pipe 12 while flowing sideways, the combustion gas in the combustion cylinder part does not pass directly upward, and the heat transfer to the water preheating pipe 4 side is carried out. Exhaust the air while increasing the pressure. On the other hand, the hot water sent to the input lower by the pump 8 is preheated in the water preheating pipe 4, reaches the maximum temperature in the discharge heating pipe 6, and is sent to the load side from the outlet 9.

されることができるなどの効果を有するものである。As described above, according to the present invention, the heat diffusion plate 1o is provided directly above the plate fins 6 without being provided in the combustion cylinder part 6, and the combustion gas is prevented from passing directly above. No. 10 is not directly hit by the flame of the combustion burner, and the same temperature distribution as before is achieved, that is, the heat transfer inside the combustion cylinder is strengthened, and the same effect can be obtained. Since the temperature of the combustion exhaust gas is low, the material of the heat diffusion plate 10 may be an ordinary heat-resistant and corrosion-resistant metal, and the cost is also low. Also,
In a heating tube fitted with plate fins, the combustion flame tends to concentrate in the center when viewed from above, but by providing the heat diffusion plate 7 directly above the plate fin as in the present invention, the combustion flame can be reduced. This has the effect of widening the concentration, avoiding local heating, and preventing the sound of boiling water caused by local heating.
