Ensure that rate of heating is maintained at the rate of 25°C per hour. Raise the temperature of flue gas at boiler outlet to 100°C and hold the temperature to up to 10 hours at 100°C for soaking refractory castables. If the temperature falls, increase the firing rate and maintain the required temperature.
As with any hot water or heating appliance, a hot water boiler system requires a constant pressure flow to maintain the optimum temperature. Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops.

Hot water boiler systems also have a high-limit temperature setting that triggers an automatic shutdown if the water temperature rises above that set point. If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.
Jul 02, 2019 · A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.
The thermostat is set to 20 degrees and the flame indicator actually goes out when the temperature reaches 19.5 degrees. Although the boiler is no longer heating the water, the radiators continue to give out heat until the room temperature reaches 20 degrees (or actually a little more).
Appliances required for electric boilers must be attached to the boilers in accordance with the following requirements: (1) A cable must be provided for grounding the boiler shell and shall be the same gauge as the incoming power line to the boiler.

With the vent valve on top of the boiler open, or in the water column piping (see Figure 2-3) open, water can now be fed into the boiler. Water used for the hydrostatic test should be at ambient temperature, but in no case less than 70°F. The appropriate hydrostatic test pressure can then be applied.
Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
