Design A Steam Utility Boiler - posted in Student: Hi everyone. I'm in my final year of my graduation, and in my project, I need steam as an utility, to use in the distillation columns reboilers (at 10 bar and 190ºC, and at 40 bar and 260 ºC). I can assume that I just buy this steam, but i would like to produce it "myself". The problem is that i don't have any kind of experience doing this.

NO x reduction is important in lowering the levels of NO x being released into the atmosphere during combustion. When a form of NO x reduction is used, it is important to have accurate measurements of not only NO but also NO 2 because the ratio of NO to NO 2 is changed. The traditional NO 2 amounts as a percent of total NOX (10% or 1.1 factor) cannot be used when NO x reducing methods are used
