We are running a natural gas fired thermal oxidiser to destroy solvent laden air from coating process. The solvents include methanol, acetone, THF, MEK, MIBK etc. Gas consumption is extremely high and we are trying to optimise temperatures at flue stack and oxidation to maximise efficiency. Has...

I am looking into improving the thermal efficiency of a thermal oxidiser burning solvent laden air (methanol, acetone etc.). I need to understand the relationship between oxidising temperature and CO NOx SOx emmisions. Has anybody looked into this ? Thanks Terry

I would like to replace an existing belt drive with a chain and sprocket arrangement. Would like to know what fluctuation in rotational speed I might get on driven shaft and how to calulate. Can anybody help with a formula for this 'polygonal effect'. Thanks Terry

Calculating expansion due to temperature is as follows :- Lc = Lo x a x t Where :- Lc = Change in length or diameter Lo = Original length or diameter a = Coefficient of linear expansion t = Temperature change For steel a = 0.000012/deg.C You need to find t so rearrange formula t = Lc /...
