Evaporation Capacity - an overview | ScienceDirect Topics

In this boiler unit, wet flue gas desulfurization is used to remove SO 2, and the low NO X burner is used to reduce NO X content in the flue gas. Therefore, the desulfurization and denitration device had no effect on our experimental results. The evaporation capacity of the boiler is 670 t/h with a design exhaust gas temperature of 120 °C. The

2. BOILERS - Bureau of Energy Efficiency

A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW) hg = enthalpy steam (Btu/lb, kJ/kg) hf = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s)

EFFICIENCY AND CAPACITY OF BOILERS - Project Gutenberg

This will be 30 pounds multiplied by the factor of evaporation for 70 pounds gauge pressure and 100 degrees feed temperature, or 1.1494. 30 × 1.1494 = 34.482, or approximately 34.5 pounds. Hence, one boiler horse power is equal to an evaporation of 34.5 pounds of water per hour from and at 212 degrees Fahrenheit. The term boiler horse power, therefore, is clearly a measure of evaporation and not of power.

CHAPTER 8 EVAPORATION - NZIFST

Jun 23, 2017 · Generally the output or evaporative capacity of the boiler is given as kg of water evaporated per hour but as different boilers generate steam at different pressures and temperatures (from feed water at different temperatures) and as such have different amounts of heat ; the number of kg of water evaporated per hour in no way provides the exact means for comparison of the performance of the boilers.
