Energy Efficient Steam Systems - academic.udayton.edu

Energy-Efficient Steam Systems. Introduction. Air, water and steam are three media commonly used to distribute heat to process loads. However, steam has several advantages compared to hot air and hot water. These advantages include. the heat carrying capacity of steam is much greater than air or water steam provides its own locomotive force.

Efficiency studies of combination tube boilers -

Efficiency of the combination tube boilers is studied by the direct and heat loss methods. It is seen that the combination tube boilers give optimum efficiency, even with the low grade fuels. From the heat balance sheets, it is observed that the dry flue gas loss is a major loss in the combination tube boilers.

Methodology for Thermal Efficiency and Energy Input

For units burning bituminous coal, EPA calculated that at least 40% of the heat input would have to come from coal and the remainder from biomass. For other fossil fuels, the heat input percentages were found to be at least 30% for heating oil and 10% for natural gas and the remaining heat input from biomass.
