The time required to heat 75 kg of water (c p = 4.2 kJ/kg o C) from temperature 20 o C to 75 o C with steam produced from a boiler with capacity 200 kW (kJ/s) can be calculated by transforming eq. 2 to t = m c p dT / q = (75 kg) (4.2 kJ/kg o C) ((75 o C) - (20 o C)) / (200 kJ/s) = 86 s
19-12-2017· Boilers heat water, and provide either hot water or steam for heating. B oilers that use radiators or in-floor pipes to distribute heat are the most common type of heating system. Before designing a heating system you need to know the heating capacity and after that calculating boiler size .

Calculation By analysing the heat output on an item of plant using heat transfer equations, it may be possible to obtain an estimate for the steam consumption. Although heat transfer is not an exact science and there may be many unknown variables, it is possible to utilise previous experimental data from similar applications. The results
04-03-2020· Where: m s: Mean rate of condensation of steam in kg/hr; W: Total weight of pipe plus flanges and fittings in kg; T s: Steam temperature o C; T amb: Ambient temperature; C p: Specific heat of pipe material in kj /kg o C; h fg: Enthalpy of evaporation or saturated enthalpy at operating pressure in kj /kg; t: Time of warming-up in minutes; Note: Suppose if the warm-up/heating time of the system is â€¦
05-12-2017· Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once thatâ€™s been determined, you can accurately select a boiler thatâ€™s large enough to heat the connected load (radiation). You only need enough steam to fill the system; any more could result in short cycling.
