Research: Heat Exchangers Cut Heating Costs by Half

CANADA - Research conducted by the Prairie Swine Centre has shown selecting the right system for heating the swine barn can cut heating costs by half, writes Bruce Cochrane.

Following a benchmarking survey conducted to assess energy use in swine barns and identify areas where energy could be saved researchers with the Saskatoon based Prairie Swine Centre compared the energy costs associated with conventional forced convection air heaters fired with natural gas, heat exchangers which recover waste heat and ground source heat pumps or geothermal systems.

Research scientist engineering Dr Bernardo Predicala says the work was prompted by concerns raised by producers over increasing energy costs.

Dr Bernardo Predicala-Prairie Swine Centre

Heating a barn is the area where most of the energy is used so as a result of that we looked at different alternative heating systems that can be applied in a barn to see if these different heating systems can translate into savings.

What we did is, over the last couple of years, we installed these different types of heating systems in rooms within our barn and we collected the actual energy consumption, the temperature, the air quality in the these different rooms under these different heating systems.

We found out that the heat recovery ventilator systems actually reduced total energy use by as much as 54 percent.

As for the geothermal heating system, we're still continuing our work on that because apart from heating it also has some functions for cooling the barn during the during the summer so we haven't done a complete trial on that aspect yet.

Hopefully when all these studies have been conducted this will lead to a significant reduction in energy use for different barn operations and, of course, a reduction in total cost of production for pig production.


Information gathered through this study is being used to develop software producers will be able to use to calculate what these various systems would cost to install and operate on their own farms.

HRS Heat Exchangers: helping to improve overall efficiency of gas compressor installations

HRS Heat Exchangers Limited, a leading heat transfer specialist for the process industries, has recently supplied Gas Compressors Ltd. with an HRS K37 multi-tube corrugated shell and tube heat exchanger for a compressor installation that maintains natural gas supply pressure to a gas turbine at the Saica Paper mills.

Gas Compressors Ltd. is a single source, plug and play, supplier offering a complete package to our clients. GCL specialise in the design, manufacture and commissioning of large and medium sized, custom built/bespoke gas compressor and booster packages for use in the Oil & Gas, Power Generation, Landfill, Water, Renewable and Petrochemical Industries. We are flexible and not tied to any particular sub-vendors, compressor manufacturers or compressor technologies.

The 4m long heat exchanger cools the 9300nm3/hr gas supply after compression, which is required to maintain feed pressure to the turbine in periods of high local demand and so ensure uninterrupted operation 24/7. The heat exchanger also condenses out any water vapour present in the gas composition.

High overall efficiency of the installation is ensured by the patented design of the HRS corrugated tube heat exchanger that achieves the required heat transfer to reduce the gas temperature from 90°C to 45°C with a very low pressure loss. The corrugated tube design also enables the heat exchanger to made considerably smaller than a comparable smooth tube unit, saving both space and cost. The combination of 32.5bar g design pressure and natural gas meant that the heat exchanger was required to meet the very demanding category IV PED (EU Pressure Equipment Directive) requirements.

Commenting on the partnership, Tony Silk, Head of Sales for Gas Compressors Ltd. stated, “We take great pride in customer service and our top quality, unique, packages. We are careful to provide the customer with their exact requirements, including delivering on time and continuity of care throughout our projects. This installation is one of a number implemented in cooperation with HRS over a period of some 10 years, an on-going partnership that helps us to maintain our very high standards”.

Priya Murray, Technical Manager, HRS Heat Exchangers explained, “This is a very demanding application: good heat transfer is normally only achieved by high gas velocity and a corresponding high pressure loss that reduces the efficiency of the whole installation. Our corrugated tube design reduces pressure loss to deliver the efficiency required and occupies less space.”

Enerji Limited (ASX:ERJ) Airec Heat Exchanger Arrives

Perth, Dec 22, 2011 (ABN Newswire) - Perth-based clean power company Enerji Limited (ASX:ERJ) advises that the first of its Airec heat exchangers has arrived in Perth.

The heat exchanger, believed to be the first of its kind in the country, arrived this week from Sweden and was shipped direct to Enerji's engineering contractor. There it will be fitted to the exhaust modifications for Carnarvon that are being prepared for installation early in the new year subject to relevant approvals. This preparatory fabrication work will result in a quicker and smoother installation in Carnarvon.

The Airec heat exchangers are a key component in Enerji's waste heat recovery system that captures heat from the exhaust gas of fossil fuel generators and feeds into an Opcon Powerbox to produce emission-free electricity. It is a similar unit to the one Enerji recently sold to a Perth public hospital project for waste heat recovery. Airec claims its heat exchangers are the most compact and efficient gas heat exchangers in the world.


About Enerji Limited

Enerji Limited (ASX:ERJ) is an emerging Perth-based green power utility focussed on commercialising the Opcon Powerbox in Australia.

The Opcon Powerbox cogeneration technology transforms waste heat into electricity and therefore creates significant energy cost and CO2 emissions savings for its customers.

Enerji has exclusive sales and distribution rights for the Opcon Powerbox in Australia and options for Malaysia, Thailand, Singapore and Sub-Saharan Africa.

The Opcon Powerbox, manufactured in Sweden by Opcon, represents a significant commercial opportunity through application to industrial, mining and power generation operations.

Heat Exchangers – the true bargain in absurdly expensive espresso machines.

Heat Exchangers – the true bargain in absurdly expensive espresso machines.
This is the start of a series of posts on why I love heat exchanger espresso machines.  Giving credit, where credit is due, I am fairly certain that I would never have found out how great they are if not for the article “How I Stopped Worrying and Learned to Love HXs” by Dan Kehn on home-barista.com as well as many other great articles over there that help you figure out how to master them.
http://www.home-barista.com/hx-love.html
That is indeed a great introduction, but hopefully this will be my own synthesis of my own impressions sorting through and expressing what my experience and my readings have led me to believe makes these machines so great.
By the way there are lots of great ones out there, but just a few that are available through roaste.com include the following
http://www.roaste.com/product/ChrisCoffee/Anita-Espresso-Machine
http://www.roaste.com/product/ChrisCoffee/Vetrano-Espresso-Machine
http://www.roaste.com/product/Nuova-Simonelli/Nuova-Simonelli-Oscar-Pour...
http://www.roaste.com/product/ChrisCoffee/Junior-Casa-DT1-Automatic-Espr...
http://www.roaste.com/product/4home/Vibiemme-Domobar-Super-Electronic-Es...
http://www.roaste.com/product/4home/Elektra-Micro-Casa-Semi-Automatica-S...
With the Anita being the cheapest on that list at an initially shocking price of  roughly $1500.
There are a few new machines out there under $1000 that might be even better bargains, such as the Silvano and CC1 (both available here on Roaste), but they are both very new and I have not gotten to use them (yet) so I cannot say if they are a better deal or not.
Now one might argue that much cheaper machines are much better deals.  For example to me, a Mazda 3 is a much better deal than any car selling for over $25,000.  (I don’t have one, but they go for half that price and will get you where you want to go as well as a $200,000 car, in the same amount of time, and perhaps even in more comfort than many of those cars).  Then again I am just not a car guy - as if you couldn't tell.
An espresso machine is different though.  Yes you can get one for $200, but can it get you where you want to go?  For me the answer is no.
