As mentioned previously, low temperature waste heat recovery faces challenges due to the relatively small temperature difference between the higher energy exhaust gas and the lower temperature heat sink. This forces a heat exchanger with a large surface area to be implemented, which will not only require more space in the gas flow stream but have a higher initial cost to the customer. Other common limiting factors include a minimum temperature for the exhaust gas of about 250 to 300 °F. This is done to prevent water vapor and other corrosive gasses in the exhaust stream from condensing. While this prevents many corrosive substances from coming in contact with the heat exchanger, a great amount of energy is contained in the water vapor and can be recovered by condensing it. Another challenge in recovering the low temperature waste heat energy is finding a feasible use for the recovered energy [4]. Methods for overcoming the first two obstacles will be discussed in more detail in the following sections and a sample system will be developed in Chapter 6 that describes different end uses and methods of transportation of this energy. Impacts of Waste Heat The obvious impact of waste heat is the necessity to purchase more energy to make up for what is wasted while performing a task. This forces the operational cost to manufacture products to rise, hurting the company's profitability or causing these inefficiency costs to be passed along to the consumer. However a less obvious impact of wasted heat is the consequences on the environment caused by a steady flow of an estimated 55.5 Quadrillion Btus/hr of energy flowing into the atmosphere from the United States alone [38]. Due to the recent rise in concern of the effects of greenhouse gasses on the environment and global climate change, the impact of energy dissipated as heat into the atmosphere has also been explored as a possible source of manmade climate change.
