hi pressure natural circulation hot water boiler
Troubleshooting a Gas-Fired Hot Water Boiler
The boiler's automatic filling system, controlled by the pressure-reducing valve, should maintain the proper water level at 12 to 15 psi of pressure. If there is no pressure-reducing valve, you can manually feed the boiler by opening up the water feed valve until the boiler pressure reaches 12 psi.

FAQ the Water Boiler Is Overheating and/or Has High Pressure
Nov 20, 2007 · If the boiler is running excessively hot, the aquastat high limit feature could have failed or the high limit setting is too high to begin with. For example, if the thermostat was satisfied and the stoker/circulator had shut down and the water temperature happened to be just below high limit, the fire in the pot could easily raise the water

High Pressure Boilers | Powertherm | Manufacturer | Water
High Pressure Boiler Working. During the circulation, the temperature of water increases as it comes in indirect contact with flue gases that transfer heat through tubes. Water circulation continues until it’s vapor pressure exceeds the vapor pressure of steam at the top of the drum. At this pressure, water gets converted to saturated steam.

Boiler circulation systems: natural circulation and forced
Natural versus forced circulation typical schematic. In natural or thermal circulation type boilers, the rate of circulation depends strongly on the density difference between the unheated water and the heated steam-water mixture. The overall circulation rate (flow) in natural circulation systems mostly depends on the following factors: - Height of the boiler - Taller boilers yield a bigger pressure difference between the heated and unheated sections and consequently produce bigger flow rates.
