circulating fluidized bed boiler operating principle

Second, the shutdown maintenance and corrosion

1. boiler after shutdown, in order to prevent corrosion of the pot must be maintained.

2. Short-term maintenance. Wet regimen employed; i.e. after the shutdown, the water will fill the furnace, the entire exhaust air.

Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam circulating fluidized bed boiler operating principle steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).

Chemical Plant Boiler Water Wall High Temperature Corrosion What types of chemical plant circulating fluidized bed boiler operating principle water wall high temperature corrosion types are there? Chemical plant boiler water wall appeared high temperature corrosion phenomenon is a complex physical and chemical processes, analyze the mechanism of corrosion can be divided into sulfate type corrosion, corrosion in chloride and sulfide corrosion three types. 1, the sulfate corrosion occurs mainly due to corrosion is sulfate type like corrosion in the boiler water wall portions of the raw coal combustion to generate a basic substance pyrosulfate and sulfate compounds such as by a chemical reaction, the corrosion process usually have junction slag or the like coking phenomenon. 2, chloride-type corrosion in recent years, many scholars have conducted research, and have achieved fruitful research results. The results showed that when the high chloride content of the fuel, will produce a certain amount of hydrogen chloride in the boiler, and the boiler corrosive effect [3-5]. Coal boiler test results show that the chemical, the chloride content is less than 2/10000, the production of coal combustion is much smaller than the chloride content of chloride corrosion is generated, therefore, not because water wall temperature corrosion caused by chlorine contained in coal of. 3, sulfide corrosion combustion zone in the furnace within the range, when the unburned flame to the water wall erosion due to chemical action, unburned fuel will consume large amounts of oxygen, so that the outer surface of the waterwall vulcanized occurrence corrosion.

SZS series circulating fluidized bed boiler operating principle in Nigeria

Recently, boilers produced by were exported to foreign countries. This time, zg provided a 15-ton SZS series steam boiler to a company in Nigeria.
