Since 1994, Intek has been the leading source of new information on condenser dynamics, which has been made possible with the RheoVac instrument. The RheoVac instrument measures the mixture of water vapor and noncondensable gases in the vent line. With this information and other plant measurables, Intek developed a Comprehensive Condenser Model and Theory (CCMT) based on physical principles. The CCMT has been validated under a variety of different operating conditions, and has been used to identify deficiencies in condenser design and problems with condenser operations and maintenance. Intek has established itself as a leader in solving condenser related problems and improving condenser performance.

COMMON CONDENSER PROBLEMS:

• High Condenser Pressure
• Corrosion
• Dissolved Gases (Oxygen, Ammonia, etc.)
• Low Cleanliness Factor
• Low Heat Transfer Coefficient
• Air In-Leakage
• Tube Fouling
• Low Pump/Exhaust Capacity
• Other Efficiency/Maintenance/Design/Operations Concerns

High Condenser Pressure

High condenser back pressure is the most obvious plant measurable that results in lost revenue or excess operating costs. Simply, back pressure is directly related to the power output from the turbines and excess back pressure means reduced efficiency and dollars wasted. Contact Us to solve your back pressure problem.

How excess back pressure affects the bottom line:

Revenue and profit loss can be significant. As shown in the charts below, even a small excess back pressure will have a dramatic impact. These results are based on a PEPSE analysis of a 525MW generating unit which shows that each 0.1"HgA rise in back pressure results in an increase of 0.17% in heat rate. In summary, a 0.3" HgA of excess back pressure, on a base loaded plant condenser, correlates to a loss of 2.68MW of power and nearly $770,000/year lost revenue.
