Circulating fluidized bed boiler, CFB Boiler for short, is widely used in coal and biomass fuel power plant. One salt manufacturing factory in China purchased the third set of 75ton/h circulating fluidized bed boiler from us. And the steam boiler model is TG75-5.29/485-M, which means the evaporation capacity is 75 tons per hour, steam pressure is 5.29MPa, steam temperature is 485℃ and the fuel type is soft coal. Up to now the CFB boiler has been operating smoothly for four years.
Due to the industry characteristics, the salt manufacturing factory needs to ensure 8000 hours/year continuous stable operation. The seller shall supply both steam and electricity to the production line. Therefore, the requirements for the CFB boilers quality and operation are quite high.
Background of purchasing the Circulating Fluidized Bed Boiler
In 2008, before purchasing the first batch of Circulating Fluidized Bed Boiler, the salt manufacturing factory investigated several excellent steam boiler manufacturers including Taishan Group. Above all, the investigation scope includes equipment manufacturing capabilities, research and development capabilities, quality management system, sales system, after-sales service system, performance, user appraisal, environmental protection data, etc. However, after comprehensive comparison, they chose to purchase two sets of 75ton/h CFB boilers from Taishan Group.
After five-month production, four-month installation and seventy-two-hour trial run, the steam boiler output capacity, coal consumption and DCS control system all met the design requirement at one time. Besides, the flue gas emission also met the government requirement. The Circulating Fluidized Bed Boiler power plant is immediately put into normal operation, thus guaranteeing the production schedule and winning the favorable comment of user.
Subsequently, Taishan Group customer service center paid a visit to the customer twice a year. We provided reasonable suggestions and guidance for the annual overhaul and maintenance. We want to make the Circulating Fluidized Bed Boiler remain the best operating condition.
In 2014, the salt manufacturing factory expanded its production line and demanded one new 75ton/h CFB boiler. By virtue of the superior product quality and excellent after-sales service, we won the project again. At present, these three sets of 75ton/h Circulating Fluidized Bed Boilers are in continuous and reliable operation. Most importantly, the dust concentration, SOX and NOX in the flue gas meet national emission requirement.
