The fuel and generation cost savings they expected and the realities of the refractory replacement costs could impact the power plant’s very existence.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also
A 600 MW PC boiler would consume about 165,000 tonnes per year of pellets co- firing at a 10% rate. At 100% pellets the consumption would be about 2.2 million tonnes per year. A typical industrial pellet mill in western Canada will produce 300,000 – 500,000 tons per year.
