Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").

Pumps Selection & Sizing

If you use on-off pump control to control the boiler water level the boiler is subjected to feedwater surges which are two to three times the peak boiler capacity. On-off pump control results in: 1) Disruption of the natural boiler circulation and firing rate.


A furnace wall of a natural circulation boiler (18m long, 76.2 mm OD and 6.1 mm thick) receives saturated water at 80 bar and 1.5 m/s velocity. Assuming a circulation ratio of 12.5 and a slip ratio (velocity of steam/velocity of saturated water) of 1.2 determine: a) the pressure head developed across 18m

Marine Boilers Steam and Water System

Steam flow diagram for an exhaust gas boiler and two oil-fired marine steam boilers. In this Marine Boilers Steam and Water System, the circulation pump "J" runs continuously. The auxiliary steam boiler serves as steam separator for the entire system. The system is thus kept in hot condition and is ready to start instantly.

The Boiler Circulatory System: Beyond the Steam-Generating Boiler

Before water can enter a steam-generating boiler, it must first be treated and cleaned of minerals and alkalis (e.g., iron or calcium) that could clog the tubes and prevent proper circulation. After the water has been treated or cleaned, it is pre-heated in feedwater ...

Water Tube Boilers

Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off. However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs.
