Comprehensive Energy Conservation Technology for Coal-fired Units
Air-cushion Belt Conveying Technology Different from conventional belt coal conveyor, the Air-cushion belt conveyor replaces conventional rollers with an air cushion formed between the belt and the bottom plate to support the belt to significantly reduce resistance. The power consumption for coal conveying can be reduced by 20%~30%. The maintenance cost can be reduced by 85%. Besides, there is a 2-3 times lifetime increase. In 2023, this technology was applied in Xinjiang Wudong Coal Min... -

Integrated Control Technology for High Temperature Corrosion on Boilers
High temperature corrosion problem has become a common problem in many large coal fired power plant boilers. It causes boiler water wall becoming thinner leading to pipe leaking and explosion accidents. According to the survey, the repair downtime of the domestic units of which the capacity are 300MW and above caused by pipe explosive accounts for about 40%. Therefore, high temperature corrosion not only affect the safe operation of the boiler, but also causes huge economic loss. The integrated high temperature corrosion control technology of LY Power can solve this problem effectively. The technology including three parts as follow.
