Aug 22, 2018 · Operation of Fire Tube Boiler. Operation of fire tube boiler is as simple as its construction. In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them.
400°C. Tube plate cracking typically starts at toes of boiler tube fillet welds and grows across the tube plate ligament from one boiler tube to another. Cracking has also occurred from centre-pop marks forming a small notch in the edge of the tube hole with expanded tubes. Ligament cracking is serious.
Oct 19, 2018 · Boiler tubes must be rolled and beading to prevent the burning of tube ends due to hot gases. Beading also increases the heat transfer rate near the tube sheet. Smaller size fire tube boilers are vertical and larger sizes are horizontal.

Boiler stay. A boiler stay is an internal structural element used inside boilers. Where the shell of a boiler or other pressure vessel is made of cylindrical or (part) spherical elements, the internal pressure will be contained without distortion. However, flat surfaces of any significant size will distort under pressure, tending to bulge.
Dec 16, 2012 · Water tube boilers are used in marine and stationary applications. A water tube boiler heats by water flowing through tubes and being heated by fire externally.

Guide to the Steam Boiler Sight Glass. The steam boiler sight glass or water level gauge allows the building owner or maintenance person to monitor the required water level in the steam boiler. A mark on the boiler body indicates the desired normal water level and a sight glass shows the current water level. [Click to enlarge any image]
Kcopp, yes the boiler has 1 circ pump on the return side to pump the water through the system. There is no pump on the supply side as the tube just goes out to the baseboards. Are you saying that if I hook up the hot water feed that it might be able to solve this problem with oversizing and short cycling?
