The problem of Feed-water for Boiler in Thermal Power Plant

Large and medium-sized boilers in the power and heat industries have high economic losses due to high operating parameters, and the original boilers are smashed. The social impact is huge. Therefore, the water quality of boiler feed water is particularly high (water quality required for power plant boilers, resistivity) >5 MΩ.CM, SiO2 <20 μg/L). In general power plants and thermal centers, water plants are set up to treat boiler feed water.

Box Group in their own development, bearing in mind the social responsibility, personally, set an example, to carry forward traditional Chinese virtues. We hope that through this way, to get more attention of the community. We work together to build a healthy growth of childhood for the children, to give them a future full of faith!

Features electric steam horizontal tube d type boiler design calculations feed water is heated by electric energy, to obtain the specified parameters (temperature, pressure) of high quality steam plant, having a high temperature under pressure, must be maintained and auxiliary components boiler (steam superheater, economizer, etc.) intact to ensure safe and economic operation. Second, scientific and rational operation of the boiler, an electric steam boiler on various wires to be contacted inevitable, therefore, be sure to check for all electrical wiring and the fastening point before the boiler, comprising a distribution cabinet, the control cabinet. Pump boiler water level gauge, pressure gauge, water level sensor, safety valve should be checked in order to start the boiler after confirmation normal.

The data obtained is calculated in the case where the fuel gas horizontal tube d type boiler design calculations fully utilized, the practical application of heat loss will be part of a more or less gas, from many angles, so when calculating the actual gas boiler air consumption, calculated in this way it may be more in line with the value of the user's actual situation.
