FORESTS, TREES & WOOD and FIRESTORM IN THE FOREST.

BOILER Wood scraps, chips and sawdust are burned in the boiler where water is super heated to high-temperature, high-pressure steam. Exhaust from burning fuel goes to the ESP for cleaning. The steam goes to the turbines.	ELECTROSTATIC PRECIPITATOR (ESP) In the ESP polluted smoke from the boiler weaves its way through a maze of positive charged electrode surfaces. These electromagnets pull ionized particles from polluted exhaust gases. Much like a magnet pulling iron filings from sand. The newly cleansed air is released to the atmosphere.	TURBINES Steam turns turbines to generate power. More than enough electricity is made to run the industrial facility. Extra electricity may be sold to power companies for community use.
HEAT Exhausted steam from the turbines provides a heating source. This leftover heat is transferred directly to the industrial heating system. Sawmills may use this moist heat to slowly dry lumber so the wood doesn’t crack.
