An approach to the utilisation of CO 2 as

The conditions for steam pretreatment of sugar cane bagasse and leaves were studied using CO2 as an impregnating agent. The following conditions were investigated: time (5 to 15 min) and temperature (190 to 220°C). The pretreatment was assessed in terms of glucose and xylose yields after enzymatic hydrolysis and inhibitor formation (furfural and hydroxymethylfurfural) in the pretreatment.

If the system is set to provide a 120°F supply, the water temperature inside the boiler's heat exchanger may reach 140°F to 160°F. As flow rate is reduced the water temperature inside the boiler will increase. This will increase the rate of lime

What is the mechanism of economizer? - ZOZEN Boiler

The lower temperature of flue gas out from stack, the heat loss will be less and the fuel which is needed to convert water into steam will be also less in certain circumstances. So it can be said that economizer can save the fuel efficiently. Economizer will make temperature of feedwater higher, so steam boiler can produce steam easily.
