Bringing this expertise into upgrading a coal‐fired facility can be part of the program to increase boiler efficiency and reduce environmental impact. For example, when a 500 MW power plant using 50 Kg of coal per second improves its boiler efficiency by 1%, coal usage can be reduced by 0.5% per second or 43.2 tons/day (15,768 tons/year).

Pulverized Coal Burner

1. Coal powder stays in the hot zone of pulverized coal burner for long time, it kinds increases the combustion efficiency. Vaporous white smoke directly gets out of the chimney instead of black smoke. 2. The heating process is shortened, rising the thermal efficiency, and low requirements on coal quality, brings high economic efficiency. 3.

2019 Electricity ATB

For the ATB, coal-CCS technology is ultra-supercritical pulverized coal technology fitted with CCS. Both 30% capture and 90% capture options are included for the coal-CCS technology. The CCS plant configuration includes only the cost of capturing and compressing the CO 2. It does not include CO 2 delivery and storage.
