How to Run a Coal Fired Boiler at the Best Efficiency

Estimated Boiler Performance and Expected Plant Performance. Converting a boiler to natural gas typically decreases boiler efficiency because of the large quantity of hydrogen in natural gas. During combustion, the hydrogen is converted to water. Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency.

Challenges when Converting Coal-Fired Boilers to Natural Gas

– Flue gas from the outlet of the boiler is mixed with the combustion air to the burners. – FGR reduces the combustion temperature and lowers the localized O2 concentration in the primary combustion zone to achieve a reduction in NOx. – Increasing the flue gas flow through the convective pass of the boiler increases heat transfer.

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

This paper will provide a synopsis of the work involved in converting three (3) boilers at the Domtar 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.
