Knowing Engine Combustion Pressure Without a Pressure Sensor
Today many industrial engines operate on a blend of fuels with inconsistent gas quality and the affect on combustion performance and emissions levels are affected. This is a case study focusing on two Caterpillar 3516 Generator Engines rated 1000VA, at 1200 rpm, lean burn gas and turbocharged, running on a renewable energy source supplementing power to a waste water treatment facility in California. The engines operate on a wide range of fuel mixture including landfill, digester gas and air blended natural gas over a heating value range from 350-650 BTU. Further the facility does not have any storage tank for homogenizing fuel blend. This study relates to our industrys future concern of variable value fuels entering the piping via the LNG market and emerging non-gas patch fields.
