  • How to Run a Coal Fired Boiler at the Best Efficiency

    Jul 05, 2009 · 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.Learn More

  • Coal: How to get the grades right on key parameters like

    Coal trading is a very competitive landscape. While end customers buy the quality of coal based on what is compatible with their boilers and furnaces, the traders need to be vigilant in sourcing and supplying right grades. Buyers impose price discounts if the coal's calorific value and other key parameters fall short of expected values. To secure the contracted revenue and avoid any Learn More
