You can expect an operating pressure of between 30 to 125 psig from a high-temperature hot water boiler. Steam boilers are used for high or low pressure system requirements. Steam boilers are best suited to applications that require high or low pressure, though some low-pressure units can be used for heat.
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.
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.
Gaskets are part of every boiler and steam or hot water system. They’re used around the many handholes and manholes provided for access and inspection, to prevent leaks in exhaust ducting, and wherever pipes are joined. If a boiler gasket fails the consequences are usually serious. Hot water, steam, or exhaust gas leaks are dangerous

It should be between seven and nine. A pH of 11 or higher will make the boiler water foam. Foaming water will leave the boiler with the steam, and that will lower the boiler's water line. The automatic water feeder will respond by adding water to the boiler. When the condensate returns from the system, the boiler will flood.
at WATER FEEDER VALVE, HYDRONIC BOILER and used on hydronic (not steam) heating boilers. But while a hydronic boiler does not normally consume water, a steam boiler always consumes water during normal operation. This means that some method for checking and keeping water in the boiler is critical both for safety and to assure against loss of heat.
Boiler make-up water treatment plant and storage. Since there is continuous withdrawal of steam and continuous return of condensate to the boiler, losses due to blowdown and leakages have to be made up to maintain a desired water level in the boiler steam drum. For this, continuous make-up water is added to the boiler water system.
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.
We have seal welded tubes in the lower drum and in a steam drum on two aux boilers (100,000 lbs per hour) without a problem. On small boilers, you typically have to seal weld all of the tubes because the heat from welding will disturb adjacent tube rolls. A two pass seal weld works nicely using SMAW or GTAW.
