2014-11-14 · Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from cooling of 50000 kg/h of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1500ºC and leave at 100ºC. The feed water is externally preheated to 180ºC before entering the boiler.

The energy released when steam condenses to water is in the range 2000 - 2250 kJ/kg (depending on the pressure) - compared to water with 80 - 120 kJ/kg (with temperature difference 20 - 30 o C).

Get a Quote2018-8-13 · The amount of steam produced by 1 ton standard coal at a boiler depends on the coal consumption and electricity consumption and they are steam boiler energy consumption indicators. Units of measurement are kg standard coal / ton of steam and kWh / ton of steam. For the actual operation of the steam boiler, the corresponding consumption indicators are generally: coal consumption should be …

Get a QuoteAs steam condenses, it gives up its latent heat and the liquid condensate retains the sensible heat. Industrial processes that use steam in heating systems must also capture the condensate to maintain a high efficiency. Therefore, the amount of condensate produced per amount of steam is a useful metric in designing and evaluating heating systems.

Get a Quote2019-4-24 · This simple Boiler model does not include a Heater section. Therefore, there is no requirement for the user to specify the fuel type or the method of heating the water and steam. However, the unit does calculate the energy required by the boiler and therefore this information can be used elsewhere to set the amount of fuel required by the boiler.
