According to the Code, how much steam must a stoker-fired firetube boiler with 62 m2 of heating surface be capable of discharging per hour?

To determine the necessary steam discharge capacity for a stoker-fired firetube boiler based on its heating surface area, one can refer to industry guidelines that specify the amount of steam produced per unit area of heating surface. In this case, the maximum allowable steam output is often calculated using standard values that are typically found in regulatory codes or engineering tables.

For firetube boilers, a common estimation is that each square meter of heating surface can produce a specified amount of steam per hour. In many jurisdictions, this value is around 35 kg/m² per hour. Therefore, by multiplying the area of the heating surface (62 m²) by this output factor, the total steam production capability can be calculated.

When performing this calculation (62 m² x 35 kg/m²/h), the result aligns with the choice of 2108 kg/h as a feasible capacity. Thus, this figure satisfies regulatory codes governing firetube boilers, especially those with a stoker attachment which might influence efficiency and output.

This understanding underscores the significance of knowing how to interpret and apply code requirements, especially in the context of calculating the operational capacities of different types of boilers based on their design specifications.
