An energy-saving boiler

Abstract

The invention discloses an energy-saving boiler, which comprises a hot water tank, an air preheating tank and a temperature resistance tank. A support block is arranged between the bodies; a combustion chamber is arranged in the hot water tank, a burner is arranged in the combustion chamber, and a flue gas heat exchange pipe is arranged in the hot water tank. The invention has high thermal energy absorption and utilization rate, improves the thermal energy after combustion of gas, and realizes the purpose of energy saving with high energy utilization rate.

Description

technical field [0001] The invention relates to the field of boilers, in particular to an energy-saving boiler. Background technique [0002] In chemical production, food processing and other fields, it is often necessary to heat water into hot water or generate steam. At present, the devices that generate hot water are basically boilers. Boilers are devices that can produce hot water in large quantities. The energy source of boilers It is mainly divided into gas, coal and electric energy. Some boilers also burn organic fuels such as garbage and straw. Among various types of boilers, boilers that burn gas and consume electric energy have the least pollution and are the cleanest boilers. However, the energy of electric energy boilers The utilization rate is not high, the energy consumption is huge, the cost is high, and the popularization and application are greatly restricted. The operating cost of gas boilers is relatively low, but the thermal energy conversion efficiency o...

[0002] In chemical production, food processing and other fields, it is often necessary to heat water into hot water or generate steam. At present, the devices that generate hot water are basically boilers. Boilers are devices that can produce hot water in large quantities. The energy source of boilers It is mainly divided into gas, coal and electric energy. Some boilers also burn organic fuels such as garbage and straw. Among various types of boilers, boilers that burn gas and consume electric energy have the least pollution and are the cleanest boilers. However, the energy of electric energy boilers The utilization rate is not high, the energy consumption is huge, the cost is high, and the popularization and application are greatly restricted. The operating cost of gas boilers is relatively low, but the thermal energy conversion efficiency of existing equipment is too low, the waste heat discharge is large, and the temperature resistance capacity is not good. Reliable, often cause burns to operators, therefore, it is imminent to propose related technical solutions
