Net-heat-input-to-plan-area (NHI/PA) release rate. As the rank of coal decreases, furnaces. increase in plan area and vertical height from the top fuel nozzle to the furnace arch. The NHI/PAs range from (1.6 x 109 J/hr -929 cm2) for severe slagging coals, through (2.2 x 109 J/hr -929 cm2) for low slagging coals.

Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow

So, Do/t = 864/26.88 = 32.14 ≈ 32 Now, we can see Do/t is greater than 10, So this is meeting the first condition Pipe having Do/t values ≥ 10. Therefore, We will follow the calculation method of first condition

Get A QuoteBarlow's formula can be useful to calculate required pipe wall thickness if working pressure, yield strength and outside diameter of pipe is known. Barlow's formula rearranged: t min = P i d o / (2 S y) (5) where. t min = minimum wall thickness (in) P i = Internal pressure in pipe (psi) Example - Minimum Wall …
