Pass dry quenching boiler circulating what are the temperature of the gas temperature requirements

Turn dry quenching furnace design, boiler outlet temperature control in 140 - a - 180 ℃, the actual exports falling in degrees is about 160 ℃, its main reason is that the boiler heating surface has a large surplus, is enough to the quantity of heat gas absorption cycle. Make the boiler thermal efficiency is further improved, increasing heating area is good. If the boiler in the long run. Caused by water quality is not very good, the furnace tube fouling or grinding powder coke turn make boiler tube or the tube furnace tube material problem arises, cut a few pipe also can continue to maintain production, the circulating gas outlet temperature without much impact.

if the boiler outlet temperature below 140 ℃, for the further absorbs the sensible heat of the coke has a lot of benefits, but also brings some negative factors: containing sulfur content in coke, part with cyclic gas circulation, in the region of the boiler heating surface temperature will produce cow dewing phenomenon, go down for a long time can furnace tube corrosion cause furnace tube blasting rate; To make a pot of Shanghai outlet temperature has dropped below 140 ℃, is bound to increase boiler heating area, from the economic analysis is unreasonable.
