Development and Operation Results of Low NOx centre dot High Efficiency Coal Fired New CUF Boiler

摘要

Recently, coal fired boiler of low NOx and high thermal efficiency are required in order to achieve both effective energy utilization and the conservation of the global environment. MHI has already developed a low NOx CUF (Circular U-Firing) boiler for bituminous and semianthracite in the pulverized coal fired boiler. The latest CUF boiler developed recently provides superior low NOx emission and highly stable combustion at low excess air. The CUF performance is enhanced by applying new combustion technology and a high fineness MRS pulverizer. This boiler achieves the lowest NOx emission and the highest thermal efficiency of any industrial pulverized coal fired boiler, and has been operating successfully since it started commercial operation in April 1995.
