Description

Heat amplification heat generator

The present invention relates to a heat generating device that is arranged in a heat exchange space in which a heat medium such as fuel and air moves to supply heat, and more particularly, to maximize the combustion efficiency of the injected fuel to improve use efficiency. It relates to a thermally amplified heat generating device.

Generally, various combustion methods are applied to suppress the generation of pollutants contained in the exhaust gas to be provided in industrial furnaces, boilers, hot air fans, cold and hot water heaters, and heaters to generate heat.

As the combustion method, a multi-stage combustion method, an exhaust gas recirculation combustion method, and a split flame combustion method have been proposed.

The multi-stage combustion method (also referred to as staged combustion) is to supply the fuel and air in stages, and in the combustion excess region, promotes the production, control, and reduction of nitrogen oxides due to the reduction of oxygen concentration and reduction to N2 (nitrogen molecules). By inducing complete combustion by supplying, there are a method of supplying air in stages and a method of supplying fuel in stages as a combustion improvement method that suppresses the generation and emission of nitrogen oxides without reducing efficiency.

However, if such a multi-stage combustion method is applied, the size of the burner increases, and thus there is a difficulty that cannot be installed in a small-sized boiler.

The exhaust gas recirculation combustion method is a method of controlling exhaust gas by recirculating the exhaust gas in a combustion zone in a combustion furnace, thereby reducing the temperature in the furnace according to an increase in the flow rate of the gas in the furnace and diluting the oxygen concentration in the combustion zone to suppress nitrogen oxide production. . However, since the amount of air mixed with the mixed gas has to be increased, the volume of the combustion chamber must be increased, and the installation area is large and the flame length cannot be adjusted.

The divided flame combustion, by changing the shape of the nozzle outlet by dividing the flame into a number of independent small flames, to increase the heat dissipation of the flame to lower the flame temperature and at the same time to form a thin flame layer to reduce the stay time , It suppresses the production of nitrogen oxides.

However, although the flame length is short in the split flame burner and the generation of unburned powder is small, there is a limitation that a large effect on the control of the nitrogen oxides of the furnace cannot be expected as a suppression principle.

Accordingly, in recent years, it has been proposed that heat generating devices are designed to minimize the pollutants contained in the atmospheric gas by improving the combustion efficiency of the injected fuel.
