26/6/2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3 ) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.

Read MoreThe mass flow rate of spray water to the first spray water group can be calculated along the same procedure: m& SHII + m& SPRAYII = m& SHIII (1) m& SHII ⋅ hSHII, 2 + m& SPRAYII ⋅ hSPRAY Figure 10 shows a flow chart with the symbols visualized of the boiler arrangement used in this calculation model.

Read MoreSince the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as W = (hg - hf) m (1)

Read Morewater holding capacity of boiler formula Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above.

Read MoreHolding capacity will always be lesser than the generating capacity. For example, for 150 ton/hr Bi-Drum oil fired boiler, Total hold up volume is around 61 tons, and Steam drum capacity is merely 13 tons ( But in running condition it will hold ha

Read MoreThis calculation translates the steam load (in pounds per hour) to boiler horsepower. Each boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5.

Read More31/5/2017 · The water holding capacity of boiler is generally 80% of the capacity of the boiler in Tonnes/Hr. Prior to 1970s, the water holding capacity of the boiler was 180% to 200%. Low reserve will respond very quickly for load fluctuation.
