Boiler Design Requirements
A boiler must meet certain requirements before it is considered satisfactory for operation. Three important requirements for a boiler are as follows:
- The boiler must be safe to operate.
- The boiler must be able to generate steam at the desired rate and pressure.
- The boiler must be economical to operate.
Make it a point to familiarize yourself with the boiler code and other requirements applicable to the area in which you are located.
Design rules for boilers are established by the ASME (American Society of Mechanical Engineers). These rules are general guidelines used by engineers when designing boilers. These rules require that for economy of operation and to generate steam at the desired rate and pressure, a boiler must have the following attributes:
- Adequate water and steam capacity
- Rapid and positive water circulation A large steam generating surface
- Heating surfaces that are easy to clean on both water and gas sides
- Parts accessible for inspection
- A correct amount and proper arrangement of heating surface
- A firebox for efficient combustion of fuel
