  • Challenges when Converting Coal-Fired Boilers to Natural Gas

    Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.Learn More

  • How to Destroy a Boiler -- Part 1

    The standard warm-up curve for a typical boiler does not increase the boiler water temperature over 100°F per hour. It is not unusual for a continuous minimum fire to exceed this maximum warm-up rate. Consequently, the burner must be intermittently fired to ensure that this rate is not exceeded.Learn More
