24 MW SLUDGE & WASTE WOOD FIRED POWER PLANT

CLIENT: Snowflake White Mountain Power Company
LOCATION: Snowflake, Arizona

The scope of this project was as follows:
1) Evaluate existing used power plant equipment for installation in a paper mill
sludge and wood waste fired power plant. Plant includes a 200,000 #/hr, 850
psig, 900oF bubbling bed boiler and a 24 MW extraction and condensing
turbine/generator.
2) Selection of all equipment.
3) Determine equipment required on the boiler to meet present DEQ & EPA
requirements.
4) Complete engineering for power plant, sludge dewatering, and wood yard
installation.
5) Project Management.

The following engineering tasks were completed as part of this project:
