During the operation of power plant boilers, it is easy to form silicide scale, calcium magnesium ion scale, and iron oxide scale, which can easily cause corrosion of the furnace tubes under sediment, long-term substandard water quality indicators, and easily lead to boiler shutdown and energy waste. To better solve this problem, our company has applied our company's proficient cleaning technology and carefully studied the cleaning technology, successfully achieving online boiler cleaning. And successfully completed the online cleaning business of circulating sulfur bed boilers such as Yankuang Guohong Chemical Co., Ltd. and Rongcheng Thermal Power Plant Co., Ltd., receiving unanimous recognition and praise from customers.
