IMPROVING OF BOILER EFFICIENCY BY CONTROLLING THE HARMFUL SUBSTANCES CONCENTRATION IN THE COMBUSTION PRODUCTS
Journal Title: Structure and Environment - Year 2018, Vol 0, Issue 4
Abstract
Chemical carbon level control is considered to be one of the simplest, cheapest and the most effective methods of optimizing fuel combustion. Standardized balance boiler’s tests show that maximum efficiency can be mentioned with highly noticeable chemical underburn responding to concentration of carbon monoxide 0.02-0.03% vol. (200-300 ppm). In addition, nitrogen oxide, which originates in maximum temperature (with lack of underburn), is 35 times more toxic than carbon monoxide. It can be supposed that defining the permissible level of chemical underburn is a typical optimizing issue due to minimize the destination function. To simplify and unify the issue, ecological and economical fuel combustion criteria were proposed as well as general energy–ecology criterion, which is simultaneously the searched destination function. Results of such research on boilers have shown that optimum combustion operation takes place within carbon monoxide concentration of 234-379 mg/m3, oxygen 4.11-4.24% vol. and air pressure 80-81 daPa.
