Product Description
I. Brief introduction of strength:
1. Quality:
A grade boiler, A1, A2 grade pressure vessel manufacturing company. All products have passed ISO9001: 2008 & ASME International Quality Management System Certification, also can provide CE, AS, GOST certification.
2. Management:
In order to ensure the quality, we strictly monitor the comprehensive quality system from raw material procurement & re-testing & process to storage. All the steels and pipes are purchased from developed countries & the well-known large domestic enterprises.
3. Welding:
Welding mainly uses advanced automatic welding, gas protected welding, TIG welding. Drum and other main pressure parts adopt CNC automatic welding, all of the welding 100% passed penetrant inspection.
4. Market:
Our products have been exported to more than 40 countries, such as Australia, USA, Japan, Canada, Russia, Thailand, Mexico, Cyprus, Pakistan, Angola, Mongolia, etc.
And supply parts for many Power Plant Projects.
II. Production Description
Circulating fluidized bed is of low-temperature combustion, therefore, nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurized during combustion process. Circulating fluidized bed boiler with high desulfurization rate is economical.
Circulating fluidized bed boiler could adopt various coal types and has high combustion efficiency, which is especially suitable for low quality, low calorific value coal.
The ash of circulating fluidized bed boiler is of high activity, thus it is easy to realized comprehensive utilization without secondary pollution.
Circulating fluidized bed boiler could adjust its load in a wide range. Lowest load can be reduced t 30% of full capacity.
