The principle and characteristics of recovery of waste heat boiler are briefly described

Waste heat boiler recovery is a equipment to recover unnecessary heat energy, is very convenient to use, energy-saving environmental protection equipment, different types of waste heat boiler functions are also different. So, what are the principles and characteristics of waste heat boiler recovery?

Recovery of waste heat boiler is one of the most direct and economical means to recycle wasted heat energy, reduce production cost and protect the environment. Boiler exhaust temperature directly affects the economy of boiler unit and the safety of tail heating surface operation. Choosing a lower exhaust temperature can reduce the exhaust loss of the boiler, improve the thermal efficiency of the boiler, save energy and boiler operating costs. However, the decrease of the exhaust temperature will reduce the heat transfer temperature and pressure between the flue gas and the working medium in the tail heating surface, and the heat conduction area will increase, and the metal consumption and the initial investment in the equipment will also increase. In addition, if the flue gas emission temperature is too low, the tail flue will condense sulfuric acid steam, resulting in low-temperature heating surface corrosion, dust blockage, so the flue gas emission temperature of most boilers is about 200 ° C.

Principle and characteristics of energy saving in recovery of waste heat boiler

1, product energy-saving principle

The exhaust temperature of the boiler is generally 120 ° C ~ 350 ° C, and 7% ~ 25% of the waste heat and 15% of the latent heat in the flue gas are not used and are directly discharged into the atmosphere. This will not only cause a lot of energy waste, but also aggravate the thermal pollution of the environment. On the other hand, the high-efficiency flue gas waste heat recovery device can not only meet the needs of processing domestic hot water or heating water, but also cool the exhaust temperature of the boiler to 100 degrees, which greatly improves the working efficiency of the boiler. It has also made due contributions to the cause of national blue sky and white cloud environmental protection.

2, high efficiency flue gas condenser product characteristics

(1) Advanced: The waste heat boiler recovery device uses superconducting heat pipe energy-saving technology, which is an efficient flue gas waste heat recovery device with independent intellectual property rights. The condensate water discharge device is specially designed to ensure that the condensate water generated in the condensation process is discharged in time, prevent the condensate water from secondary evaporation, and ensure the recovery efficiency of the waste heat recovery device.

(2) Energy saving: The use of new heat exchange fins, heat exchange components and condensate drainage structure can fully recover the latent heat of the flue gas, the exhaust temperature can be reduced to 40 ° C ~ 80 ° C, the total pressure drop is small, and the power consumption is small.

(3) Beautiful appearance: Due to efficient heat exchange components and reasonable structural configuration, light weight, small size, beautiful appearance.

(4) Durability: Construction series gas boiler flue gas condenser exchange heat pipe is made of stainless steel with high efficiency anticorrosion, giving full consideration to thermal stress, anticorrosion performance, strength, etc., to ensure the safety, reliability and stability of the equipment.

(5) Cost savings: Generally speaking, the investment cost of installing the equipment can be recovered within 1 to 2 years, and you can benefit from energy savings after 2 years, bringing considerable economic benefits to users.
