What You Need to Know About Boiler Condensing Economizer
If you are looking to save energy, as you can’t keep up with your bills anymore, you should consider investing in a boiler condensing economizer. What you have to do before you decide on which boiler to get is determine the capacity of the boiler, the steam production, the stack gas temperature, fuel consumption, hours of operation and the combustion efficiency. It is also vital that you discover your in-plant uses for the water; some examples are preheating, makeup heating, process heating and domestic water heating. Once you have distinguished what you need the boiler condensing economizer for, it will be easier for you to make a decision.
It could be residential purposes that you need the boiler for, or it could be industrial, either way, you must know exactly what it will be used for before you can search for the right boiler. Cast iron boilers are the most popular ones to use; they are durable, reliable and affordable so keep this in mind when you are shopping for the perfect boiler. Another aspect you have to take into consideration before purchasing is the thermal requirements to be met through installing an economizer boiler. Cost savings as well as fuel energy are important factors too and should not be neglected.
What you should do is obtain quotations from different companies, but make sure that the quotation includes the installation as well as the boiler itself, unless you know how it should be installed. However, even if you do know a little about boilers, it is not advised that you attempt the installation yourself, but rather get a professional in to do it for you as that way you know that it is done properly and should something happen with the boiler after that you can call them back to fix it and it won’t be your fault, nor should you have to pay for it if the problem stems from the way in which the installation was done.
The heat in the exhaust gases that is available in a boiler condensing economizer will depend on how much hydrogen is in the fuel, it will also depend on the fuel firing rate, the stack gas temperature and the amount of excess oxygen found in the flue.
If a boiler plant is able to provide as much as 500,000lbs of much needed steam for the heating system, the best system to use here would be a direct contact boiler. This is one of the condensing economizers, so it should all work out just fine. This should save anything up to about 20MMtu, but of course this amount would depend on the boiler load used at one time. Due to the fact that the condensate will not go back from the heating system, energy that is recovered will be used further, to heat the plant makeup water.
A boiler condensing economizer will benefit you in more ways than one; not only is it cheaper to have, but it is also easy to use. You will be much happier with the performance of one of these boilers compared to that of a traditional boiler system.
