Guide: Industrial production produces a large amount of high-temperature flue gas. The emission of flue gas into the atmosphere not only pollutes the environment, but also causes a lot of waste. Therefore, users will use waste heat boilers to reuse the flue gas to produce hot water, steam, etc., for life and produce. What are the conventional configurations of waste heat boilers? Generally, steam boilers need to be equipped with boiler feed water pumps. How to select the type of feed water pumps?

Generally, steam boilers need to be equipped with boiler feed water pumps. How to select the type of feed water pumps?

  Waste heat boiler  is a device that uses waste gas generated from heating furnaces, boilers, coke ovens, etc. to realize waste heat recovery and reuse. Its key equipment includes a heat exchanger for waste heat recovery, also known as a waste heat boiler body, a steam drum, a deaerator, a feed water pump, a circulating pump (if not required for natural circulation), as well as connected pipelines and auxiliary equipment. The thermal principle is the principle of the heat exchanger.

  The advantages of waste heat boilers are mainly energy saving and emission reduction. The full utilization of heat, on the one hand, considers the characteristics of the boiler to ensure a more full utilization of heat; on the other hand, it also reduces the cost of fuel consumption. Secondly, it also reduces the emission of nitrogen oxides. At the same time, the flue gas treatment device of the waste heat boiler will also simply purify the exhaust gas.

2. Selection method of boiler feed water pump

  The so-called standardized boiler feed water pump is the latest model of boiler feed water pump developed and promoted by the country in accordance with the requirements of ISO. Its main features are small size, light weight, excellent performance, easy operation, long life and low energy consumption. It represents the latest trend in the current boiler feed water pump industry.

  1, flow=(spare factor 1.2)×【(maximum load water consumption of boiler)+(boiler blowdown volume)】

  2, head = the opening pressure of the safety valve of the boiler under the designed pressure + the resistance of the boiler economizer and the water supply piping system + the maximum and minimum water level difference of the water supply system

  3, the water supply temperature-the water supply temperature is normal temperature, no special requirements are needed when selecting, and the water supply temperature is >100℃, the water supply temperature should be emphasized when selecting the water pump

The selection method of waste heat boiler and feed water pump is introduced above, and it is hoped that users can have a deeper understanding of waste heat boiler and water pump through this article. According to different pressures, waste heat boilers are also divided into normal pressure and pressure-bearing, and pressure-bearing waste heat boilers must be installed and used in strict accordance with the pressure-bearing boiler specifications.
