cfb boiler Agent tube erosion protection coating

A note on large-size supercritical CFB technology

2020/3/1 · In China, the first 600-MW (25.4 MPa/571 C) CFB boiler, which was, at the time, the largest CFB boiler in the world, was put into operation at the Sichuan Baima Power Generation Plant in April 2013. Cheng et al. [ 7 ] summarized the rationality and adaptability of a CFB boiler, in combination with the supercritical circulation technology, as compared to a pulverized coal boiler.

The FeCr-Based Coating by On-Site Twin-Wire Arc Spraying

The wear behavior of the coating was evaluated by ball-on-disk wear test at both room temperature (RT) and tube service temperature of 300 C. The results show that the coating is characterized with composite-like structure of oxide boundaries and FeCr solid solution, with hard phase of borides embedded within FeCr phase, resulting an average microhardness of 10.80 GPa.

Boiler Corrosion Prevention for Waste & Biomass Boilers

Refractory protection is the first defense against corrosive flue gases and can also have excellent erosion properties, but has limited heat exchange properties as the thermal efficiency is low. Refractory alloys can be used, but due to the excessive material costs and limited erosion resistance, the implementation of the surface protection layer is often a more cost-effective solution.
