  • Furnaces and Boilers | Department of Energy

    Energy efficiency upgrades and a new high-efficiency heating system can often cut your fuel bills and your furnace's pollution output in half. Upgrading your furnace or boiler from 56% to 90% efficiency in an average cold-climate house will save 1.5 tons of carbon dioxide emissions each year if you heat with gas, or 2.5 tons if you heat with oil.Learn More

  • How to compare Natural Gas Boiler and Coal Boilers?

    Apr 05, 2017 · There are not many commercial or industrial coal fired boilers left, but where they exist the load is substantial and the equivalent gas energy usage is measured in the millions of MCF per year. These boilers are typically at least 50,000 lbs of steam per hour (1,000 HP) and larger. They are typically located at very large industrial facilities, paper mills, large food …Learn More

  • Expert systems and coal quality in power generation

    system is the method used to optimise the coal combustion in the boiler.
