Troubleshooting a Gas-Fired Hot Water Boiler

The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure. If there is no pressure-reducing valve, you can manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi.

BOILER BASICS AND TYPES OF BOILERS, DIFFERENCES

A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.

Low Pressure Boilers Ch.9 Questions and Study Guide | Quizlet

Hot water heating systems require less water than steam heating systems. The natural circulation hot water heating system uses circulating pumps to transport water in the system. Water becomes less dense as it is heated. The natural circulation hot water heating system uses a compression tank to absorb pressure changes.

Colder feedwater replaces the water that rises, which creates the natural circulation. A typical boiler circulation (as shown below) will illustrate: Boiler feedwater being introduced into the steam drum. Cooler water sinking through tubes called "downcomers." Water absorbing heat from the tubes, then the heated water rising to the steam drum. Due to the critical need for water, modern boilers are equipped with automatic low-water trip switches.

Difference Between Low- and High-Pressure Boilers | Hunker

High-Pressure Boiler Definition. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.

Troubleshooting a Circulator Pump | DoItYourself.com

Troubleshooting Your Boiler Circulator Pump. A heating circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework.
