    Ca-3 i’ve always just eyeballed the flame. Is it really important to do combustion testing? Looking at the flame color, shape and stability has been used as a “rule of thumb” for many years but eyeballing will not allow you to opti- mize the efficiency, safety, or environmental compliance of your eq...

    Ca-7 i know that o 2 , co, co 2 , temperature and smoke can tell me a lot about combustion. How do they all relate to efficiency? Theoretically, peak fuel efficiency is achieved by “per- fect” combustion, also called the stoichiometric mix (see charts #2 and #3). If it were possible to have perfect ...

    Typical draft overfire measurements* (0.02 inches h 2 o) and flue draft measurements** (0.04 to 0.06 inches h 2 o) insure that there is continuous negative pressure in the combustion system. Excess draft will increase your stack temperature and decrease your combustion efficiency. It is important to...

    Ca-15 in an oil fired furnace, when do i measure smoke? Smoke is best measured when the burners have stabilized, normally one minute after ignition for small combustion equipment. Ca-16 can oil furnaces and boilers produce co? Oil burners, and any other piece of combustion equip- ment, will produce ...

    Cs-3 how can i prevent carbon monoxide poisoning? The best way to prevent carbon monoxide poisoning is to make sure that your combustion equipment is func- tioning properly. Combustion air openings (vents, flues, exhausts and ducts) must be kept open, clean and free of blockages such as dirt, dust, ...

    Cs-8 how do i check for a cracked heat exchanger? Visual inspection of the heat exchanger should always be done first. It may not be possible with visual inspec- tion alone to make sure that the heat exchanger has no cracks or pinhole leaks caused by corrosion. One sign of a cracked heat exchanger i...

    Ec-3 what is the difference in no and no 2 in stack gases? Nitric oxide (no) and nitrogen dioxide (no 2 ) are the toxic gases which constitute no x . All combustion processes can produce no x . No x emissions contribute to the formation of acids in the earth’s lower atmosphere; these acids contribut...

    T e c h n o l o g y tc-1 i’ve always been able to get along by eyeballing the flame. Why should i use a mechanical or electronic instrument? As amazing as the human eye is, it is not capable of per- forming quantitative analysis of changing colors in widely varying surroundings and situations. The o...

    Tc-6 how often do i have to calibrate my electro n i c i n s t ru m e n t s ? Calibration consists of zeroing and spanning sensors. The co, no x and so 2 sensors are zeroed automatical- ly in some instruments. Simultaneously, the oxygen sen- sor is automatically spanned of 20.9 o 2 in air. Most manu...
