The ABCs of PRM
F is for Flare System
PRM Flare Systems are used for controlling Methane (CH4) and Carbon Dioxide (CO2), as byproducts of Landfill Biodegradation. PRM specializes in designing and manufacturing flares for landfill applications up to 10,000 SCFM with destruction rates of up to 98% efficiency. Other markets include waste-water and agricultural applications. PRM has been manufacturing flares for 20 years and has many utility and enclosed flare systems operating throughout the USA and Canada.
Utility Flares
The Utility Flare or “Candlestick Flare” is a basic flare that is used primarily for the combustion of excess landfill or other biogas generated by solid waste landfills. Candlestick Flares burn the concentrated fume which is typically 40%-55% Methane by discharging the gases through a discharge pipe and through a windshield. As the gases discharge, they are exposed to a pilot that will initially ignite the gases. Sustained combustion is typical without a pilot, however, the pilot is available to actuate as needed. Candlestick Flares are typically monitored by a thermocouple or a UV Flare scanner for flame activity. Our Candlestick Flare can achieve efficiencies greater than 98% when operated properly.
Enclosed Flares
PRM Enclosed Flares combust the gases inside a vertical, insulation-lined chamber. Enclosed Flare designs increase destruction efficiencies and allow sampling to confirm destruction. This can be important to insure compliance and optimize carbon credits. Typically, an enclosed flare would be used because of regulatory requirements or for greater aesthetic appeal as the flame is not visible. Capacities from 250CFM to 10,000CFM. For applications requiring strict NOx compliance, PRM can design the Enclosed Flare with staged burners and injection systems.
Rental Flares
PRM has flare skid systems available for short or long term rental. PRM rental flare system consists of a blower skid, blower, knockout tank, and controls. Renting a flare system allows a pilot test to establish the flow capacity of the landfill. Based on these results, a permanent flare can be designed.
