Thesis Question
What is the most efficient waste heat recovery method for homes in Kamloops. (existing or new builds)
Abstract Rough Draft
This is my analytical report, abstract outline rough draft; the technology I am researching has been foolishly ignored for too long. This report will be useful for home builders wanting to take an aggressive approach to GREEN initiatives.
Abstract Outline – Waste Heat Recovery
The priority of being energy efficient is becoming increasingly more important to the global community. This over-looked technology could save billions of dollars around the world, within any application where heat is produced as a bi-product. Waste heat recovery innovations are continuously being thought of, designed, and tested for several applications.
Project: Determine the most efficient waste heat recovery process for residential building applications in Kamloops.
Heating of buildings can be accomplished through;
Geo-thermal systems
Boiler HVAC systems
Natural Gas Furnaces
Waste heat recovery systems
Method:
To determine the most beneficial use of waste heat recovery in residential applications, the examination of the following will need to take place:
1. Environment Impacts
The use of a waste heat recovery system drastically reduces the amount of fossil fuels or electricity required for heating a house. Therefore, a recovery system enables a house to decrease its carbon footprint substantially.
2. Construction Costs
The installation of a waste heat recovery system would increase costs minimally; however, the money spent initially would be recovered quickly through decreased energy consumption.
3. Energy Savings
Through the use of waste heat recovery from various sources such as AC units, furnaces, and hot water drains; houses and entire neighborhoods will see savings of huge numbers on all energy bills.
Special Problem
Require a way of accurately measuring energy savings, by looking at initial costs then subtracting the savings through waste heat recovery. The lack of this equation is due to minimal use of renewable energy technologies.
A formula has been derived for heat recovery from heat treatment furnaces. For example a heat treatment furnace has exhuast gas leaving the furnace at 1000*C @ 2200 cubic meters per hour. At 150*C final exiting exhuast temperature the total heat recovered can be calculated as follows.
Q = V x p x Cp x delta T
where:
Q = heat content in kCal
V = flowrate of the substance in cubic meters/hr
p = rowe, density of the flue gas in kg/cubic meter
Cp = specific heat of the substance in kCal/kg *C
delta T = temperature difference in *C
Cp = 0.24 kCal/kg/*C
Q = 2200 x 1.19 x 0.24 x (1000-150)
= 534072 kCal/hr

WASTE HEAT RECOVERY
Heat losses must be minimized before waste heat recovery is investigated. The most commonly used waste heat recovery methods are preheating combustion air, steam generation and water heating, and load preheating.
BENEFITS FOR FURNACE RECOVERY
Benefits of waste heat recovery include:
• Improved heating system efficiency. Energy consumption can typically be reduced 5% to 30%
• Lower flue gas temperature in chimney. Less heat is wasted.
• Higher flame temperatures. Combustion air preheating heats furnaces better and faster.
• Faster furnace startup. Combustion air preheating heats furnaces faster.
• Increased productivity. Waste heat used for load preheating can increase throughput.
Potential Applications
Waste heat recovery should generally be considered if the exhaust temperature is higher than 1,000°F, or if the flue gas mass flow is very large.

I am sure you must have some good ideas after the field trip. Remember to post you planning outline and start researching the different methods of heat recovery so that you will know what to include in your report and what to exclude.
Matt,
Chapters has a book that could help your research, it is:
Wood Carbonization Unit:Design & Development of a Prototype with Recovery of Waste Heat
matty hows life?? haha sweet blog..
UHm looked on the net found a PDF for you...
http://www.em-ea.org/Guide%20Books/book-2/2.8%20Waste%20Heat%20Recovery.pdf
hey matt. i found this site and it came up with a whole bunch of acoplishments that waste heat recovery has done. And there is a whole bunch of information there for you too. http://wasteheat.com/
Hey Matt. hey thanks for the post, but im doing mine on people building new houses in the neighborhood, and or tearing down the old heritage homes to make a huge block house. Morgan could use those pictures and whatever else you have to do with heritage home renovations though, thats here topic.
Here Matt, here is a better site i think for you. it has a bunch of different topics on waste heat. Maybe it will help you out.
I think that you could narrow your topic by, "Benefits to waste heat recovery loss in dry climate type areas." (such as kamloops)
-you might want to look at differen methods used?
-Cost of each?? is it worth to spend more for better quality??
Hope this helps.
You may want to look in on electric heat pumps. There is a book called "Electric Heat Pumps in Waste Heat Recovery Systems" by the Edison Electric Institute. More infor can be found at the Edison Electric Institute website http://www.eei.org/search/index.htm?search=heat+pumps. I hope this helps
hey matt,
there are some towns in Germany, one called Jühnde and one called Dardesheim that use all sorts of alternate energy sources to run the villages. check out this link: http://www.magazine-deutschland.de/issue/Doerfer_3-07_ENG_E1.php
to read about Juhnde and their biomass uses. or just type in german town biomass into google and you will find articles on them. Temperatures in Germany are similar to here, although im not sure about the desert part, so hopefully you can find some good research info there.
Does it make a difference when utilizing heat recovery if the climate is dry? The temperature certainly matters, but I am not sure about the humidity.
I found some info that might help you out..

Hey Dustin thanks for the interest in Waste Heat Recovery, that site has some good info, I'll be able to use. I found a source for you,

Dale good call buddy, that definetly clears up and narrows my research down, with noting that temperature does matter in waste heat recovery, but moisture levels dont. Thank you
Hey Shevaun, thanks for the energy sufficient sources. Unfortunetly Im researching waste heat recovery, not self-sustainability within residential applications.
But anyways I found an info source for you, it discussed Lead poisoning in houses. Hopefully its useful.

Hey Justin buddy, thanks for a couple bites, these look like good info pools. It also will help me narrow my research down. I found a sweet site for you. It a large network of information about many issues with Monolithic Domes. Such as HVAC issues, Structural detail choices (rebar points) and other problems that are by-passed with these domes.

Hey Natasha, sorry I took so long to reply, thanks for the book recommendation. I have found some information for you, its an example of a jail build with references to material suppliers and construction team list.
Here is the URL.

Hey man this book should help u out as far as industrial buildings go on heat waste recovery. Seems to have a lot of information according to reviews

Hey Brian,
thanks for the book reference, I should be able to use the industrial waste heat recovery technology for residential applications.
