Abstract: This paper, based on testing fuel quantity and components, air quantity, smoke components

and exhaust temperature, uses energy analysis of steam generator to calculate the positive

and reverse balance efficiencies at a maximum error 254%. Energy consumption analysis is

conducted to find the major factors of steam generator efficiency, which plays a vital role

in finding energy consuming processes and exploring saving energy. Fuel quantity in the

overheated steam generator is calculated as the same steam quantity is generated. When

generator is running, excess of air is the key factor impacting generators efficiency,

which may be largely increased by recovering the heat of nitrogen in the exhaust and

sensible heat in the steam along with recovering the latent heat of steam. The same fuel

will produce more wet saturated steam than overheated steam, and more fuel is consumed to

produce overheated steam with the same steam quantity.

Key words: SAGD, overheated steam, steam generator, energy consumption analysis
