Upvote # 2 10-15-13, 03:22 PM F Furd Member L404T,V PressureTrol Controllers are for use on oil burner systems for pressures up to 1035 kPa or 150 psi. It opens on a pressure rise above its operating set point that is above the low-gas pressure setting and above the normal operating gas pressure when full input is achieved. That means we should be able to get steam to the end of the 200-foot run with just two ounces of pressure.
Ship Emergency Generator Load Testing Methods, Reason why exhaust outlet temperature of an engine cylinder unit maybe higher than other units. The burner stays off until the pressure inside the boiler drops to the differential (2 psi) setting minus the setpoint. As you drive you regulate the gas pedal to match a speed you desire, and a modulation control for a steam boiler does the exact same thing. And some long-gone heating professional figured that out already. Its 200 feet wide, 100 feet deep and five stories tall. Lets start by explaining this two controller types. Have your product or service seen by tens of thousands of heating professionals every month. Why does it matter if the cutout dial is set to 1 or 1.5 if everyone says the boiler should (will almost never) reach above that pressure anyway before the thermostat hits the set point? The quick and short is that I think the technician set the pressure too high during my recent annual service. Dan Holohan and his wife, Marianne, founded www.heatinghelp.com in 1997. differential.
