Description

Single heat source multiple heating system

The present invention relates to a heating system that can use a single thermal energy to select different thermal energy generators for heating, and can save energy.

At present, the general boiler structure mainly includes a furnace body and a combustion chamber and a fluid chamber inside. The fluid chamber can contain the working fluid to be heated. The working fluid can be hot kerosene, steam or hot water, respectively. The workflow system is introduced from an inlet and then exported from an outlet. Fuel can be placed in the combustion chamber to heat the working fluid in the fluid chamber, and the heated working fluid can be provided for various other purposes. After the fuel is burned and heated by the fluid chamber, it is discharged to form waste heat. Since the temperature of the waste heat is quite high, waste heat will be wasted.

In order to effectively utilize waste heat, a boiler is usually installed in common boiler equipment on the market. Assuming that the boiler requires 3 million kcal/hr of heat energy, the burner must provide 3 million kcal/hr + 5% heat loss + 5% efficiency loss = more than 3.3 million kcal/hr, so the actual heat energy provided by the burner should be More than 3.5 million kcal/hr. In addition, the economizer used in the boiler recovers about 5%, which is equivalent to 150,000 kcal/hr. The heating system required by the boiler is 3.5 million kcal/hr, and the heat energy output is 3.15 million kcal/hr, with an efficiency of approximately 90 %. Boilers generally use heating and water supply, which is calculated as 6T (3 million kcal/hr) × ΔT = 150,000 kcal/hr, ΔT = 25°C, that is, the boiler inlet water can be increased from 25°C to 50°C for output use.

The waste heat generated by the boiler can provide preheating for the passing air. The air heating of the group and the preheating of the water passing through the water preheating group. The preheated high-temperature air and water can be respectively introduced into the combustion chamber and hot water chamber of the boiler, thereby reducing fuel consumption and shortening the heating time to increase Heating efficiency.
