boiler safety and role of low water leve

Boiler Safety and Role of Low Water Leve

Low-water level conditions in the boiler occur when the water in the boiler drum falls below the low water level mark. Such conditions have the potential to severely damage the boiler. The furnace temperatures usually exceed 1,800°F (980°C).

May 01, 2018· An easy rule of thumb when attempting to calculate the boiler’s steaming rate is 0.5 GPM for every 1,000 square feet of equivalent direct radiation (EDR). This means water is being taken out of the boiler in the form of steam, at a rate of 0.5 GPM for every 1,000 square foot rating of the boiler.
