The pollution control hierarchy places pollution prevention well above end of pipe pollution control, so reducing energy consumption is the primary way to approach reducing this significant portion of the world’s emissions. In addition, energy conservation meets the most fundamental requirement for a successful large scale emission reduction program – that being a return on investment (ROI) for an emission reduction project.
Condensing heat recovery technologies can easily provide boiler plant efficiency improvements of 10% to 20%, with a directly proportional decrease in all PM2.5, greenhouse gases, and other pollutants. In addition, direct contact condensing heat recovery units (which are wet scrubbers designed for heat recovery applications) can simultaneously provide significant end of pipe reduction in total particulate matter (TPM), PM2.5, and SO2 emissions.
This paper describes a verification program conducted on an existing installation at the Stratford General Hospital in Stratford, Ontario. During normal winter (high load) operation of the boiler plant equipped with a FLU-ACE direct contact condensing heat recovery system, the impact of the system on the boiler plant energy efficiency, and the end of pipe reduction of TPM, PM2.5, and SO2 were simultaneously measured during firing of natural gas and #2 fuel oil.
This paper presents the method and results of this verification program.
