Determining the rated steam pressure of a gas-fired steam boiler can be summed up in one sentence: The steam pressure must meet the maximum working pressure required by the equipment that uses steam. Here I’ll give you a simple, practical and pitch-free judgment method.

1.The most crucial basis: How much pressure does your steam-using equipment require?
Steam pressure is neither the higher the better nor the lower the better; it should match your equipment.
You just need to check the nameplate of the equipment you use steam. It usually states: · Working pressure (MPa); Maximum allowable pressure (MPa).
The rated steam pressure of the boiler must be greater than or equal to the maximum working pressure of the equipment.
For example: If you have a sterilizer that requires 0.7MPa, then the boiler should at least be selected at 0.7MPa.

2. If the pressure of the equipment is unknown, it can also be judged by empirical values
The following are typical stress requirements in common industries:
· Food processing (steaming, double-layer pot) : 0.4-0.7MPa
· Washing and ironing industry: 0.4-0.6MPa
· Pharmaceutical industry: 0.6-1.0MPa
· Chemical industry: 0.6-1.25MPa
· Heating: Atmospheric pressure boilers are generally employed.(0mpa)
If you don’t know the pressure of the equipment, you can tell me your industry and I can directly recommend a suitable pressure for you.
