What is the total relieving capacity required for a watertube boiler with a total surface of 95 m2 and a superheater surface of 20 m2?

To determine the total relieving capacity required for a watertube boiler, you can use the general formula that considers both the total heating surface and the superheater surface. A common approach is to use the surface area to calculate a capacity in kg/h.

In this specific case, a watertube boiler with a total heating surface area of 95 m² and an additional superheater surface area of 20 m² allows for effective heat transfer, which helps in calculating steam generation capacity.

The total surface area is the sum of the boiler's heating surface area and the superheater area, resulting in a total effective surface area of 115 m² (95 m² + 20 m²). Based on industry standards, the steam output capacity can be approximated, generally expressed in kg/h.

For watertube boilers, a rough conversion factor commonly used is around 80 kg/h of steam produced per m² of heating surface area. Therefore, for a total surface area of 115 m²:

115 \text{ m²} \times 80 \text{ kg/h/m²} = 9200 \text{ kg/h}

However, the total relieving capacity required may also depend on operational conditions and
