How to compare Natural Gas Boiler and Coal Boilers?

Jan 05, 2018 · Modifying an existing coal-fired boiler to natural gas firing capability, either to replace or to supplement coal as the primary fuel source, is an extensive – and expensive – project. Although each project is different, the scope of the conversion will ultimately determine the installation costs. Capital costs can be offset by several factors.
