Boiler – Fundamentals and Best Practices

Total Heat of Steam = Sensible Heat + Latent Heat of Vaporisation Specific Enthalpy : Steam = Water + Evaporation Thus the Total Heat of Steam (Specific Enthalpy - Steam) is 2,676 kJ/kg (1151 Btu/lb) This data is found in Steam Tables. Steam.

Plant Engineering | When to use electric steam boilers

The cost to operate the central boiler at 30 bhp is 1.338 mcf/hr x $7.00/mcf = $9.37/hr. Piping losses are ignored since the boiler has plenty of excess capacity to overcome these losses at the minimum turndown ratio. For oil fired boilers, the situation is similar — fuel prices vary by locale and supplier, and are prone to future increases.
