Three Ways to Optimize Solid Fuel Combustion - Hurst Boiler

The fundamental justification behind purchasing a solid fueled boiler is that the fuel used is a cheaper alternative to oil and gas, which can lead to faster payback rates. Years ago, all boilers were solid fueled; however, the convenience of oil and gas piping along with declining fuel prices, rising labor costs, and strict EPA regulations has raised questions as to which type of boiler will

Temperature Considerations for Pressure Relief Valve Application - National Board of Boiler …

When low temperatures may be encountered, materials appropriate for this application must be selected. Particular attention is called out for application of carbon and low alloy steels when used below -20° F. Impact testing of valve body materials may be required, and alternative materials with better impact resistance characteristics are often selected for low-temperature applications.
