WASTE HEAT RECOVERY BOILERS - Johnston Boiler

Jan 14, 2019 · Low-water trips are generally installed approximately 6" lower than normal operating level. The control of the boiler water level is tricky and even the best tuned control systems cannot always prevent a low-water condition The "water level " in a pressure vessel is actually a fairly unstable compressible mixture of water and steam bubbles that will shrink and swell with pressure changes …

Common Boiler Problems, Part 1: Low Water Conditions

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

Water Levels in Steam Boilers | Spirax Sarco

In horizontal shell boilers, the water level rises with increasing load (due to the presence of more steam being below the water level in the boiler). As it does so, the water surface area (steam release area) will decrease because, as the water level is above the centre line of the boiler, …
