Re-Powering Paper - Coal-to-Gas Boiler Conversion

Nekoosa Paper Mill from coal to natural gas firing. Units 1 & 2 at the facility are wall-fired steam boilers rated for 110,000 pph main steam flow each. Unit 10 was originally a stoker fired coal and bark boiler rated for 225,000 pph main steam flow. In 2014, all three boilers were converted to fire natural gas only.

Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.
