Normally in a steam boiler system, the top and bottom valves from the sight glass should be open at all times. Water is not added through these valves instead a separate water supply should be present which fills the boiler. Usually a half copper water line is connected to the steam boiler. Water can be added slowly when the boiler is not hot.
A water seal trough is essentially an expansion joint between the boiler and bottom ash hopper. The trough contains a seal plate typically made of Inconel® Alloy 601, Inconel® Alloy 625, AL6XN®, or Type 316L Stainless Steel. During the transition between a boiler's cold state and constant burning, the seal plate 'grows down' to the bottom of the seal trough, which in conjunction with water, creates an air seal.
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.
Concentration is so bad that sight glasses are pitch black, looks more like ink than boiler water. Boss will not lose his job, this is a Veterans Hospital. Historically, all his experience till recently is HVAC, with very little hot water heating boiler and no steam plant experience at all. Besides that, I like the guy. Thanks to all of you.
I have a Burnham iron boiler dating from 1989 for my single family residential steam radiator system which has developed a leak. The steam condensate drips down onto the burner tubes and of course, steams off into the exhaust vent, turning the exhaust into a steam condensate cloud on cold evenings and mornings.
This “Hybrid” WHR boiler with supplemental fuel burners generates heat continuously to meet plant steam or hot water requirements. During periods when the heat content of waste exhaust gas is insufficient, the sup-port burner will fire to provide steam within the desired range of operation. Find out how you can get the most out of every BTU.
In a coal fired boiler, a large clinker falling into the bottom hopper can lead to a furnace seal breakage. The large clinker fall results in an appreciable volume of steam production from the water trough of the bottom hopper which pushes out the water from the seal area. The seal water can evaporate due to make up water being low or blocked.
