What is the relationship between water quantity and steam quantity of gas-fired boiler?

First of all, the boiler water and steam are two concepts. It is the unit of measurement for boiling water boiler. What is a boiled water boiler? It belongs to the category of normal pressure hot water boiler, which heats the water temperature to boiling state. To ensure safety in use, the top of the boiler is provided with a nozzle communicated with the atmosphere. If steam is discharged automatically, the boiler will always work under normal pressure, so its attribute is normal pressure hot water boiler.

Steam quantity, also called steam dryness, is a thermodynamic property, which can quantitatively describe the ability of steam to produce mechanical energy. Steam quantity in fluid is defined as the ratio of steam mass to total mass.
