Evaporator and Recovery Boiler Energy Efficiency white

Estimated Project Approved Lifetime Recipient Recipient

Heat Recovery & Boiler Replacement This energy project is to include high temperature heat recovery from a new ammonia engine room and make changes to the hot water system to improve it's efficiency and use. This demand reduction is expected to allow the existing coal boiler operating at 8MW to be replaced with a 6MW biomass boiler.

INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.

Black Liquor Gasification - National Energy Technology

The older method to recover this energy involved concentrating the solution to about 75-80% solids by weight and then burning in a recovery boiler to generate steam. A gasification system, however, can feed the liquor into a high-pressure gasifier to produce electricity, steam, or potentially any other gasification product.
