Oct 25, 2021 · Another boiler high pressure issue. Hello, Last week I've noticed the pressure relief valve dripping water and the boiler pressure was over 30 PSI. I turned the boiler off and waited for it to cool down. The pressure did not go down, I drained about 5 gallons of water to bring the pressure down to 15 PSI. When I tried checking the expansion

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
