Controlling the flow rate of heat transfer oil under different operating conditions in boilers
Thread Content
When the heat transfer oil furnace is operating normally, to prevent coking of the heat transfer oil, it is necessary to maintain safe flow rates of the heat transfer oil in the radiation section and the convection section. During the planned shutdown process, as the furnace temperature gradually decreases, is it still necessary to maintain the original flow rate of the heat transfer oil? If several pumps are connected in parallel, could reducing the number of operating pumps be considered? For energy-saving reasons.
With the fuel supply stopped, the furnace temperature drops to a safe level, allowing the flow rate to be reduced.
Generally, a low flow rate can affect the furnace; since the furnace has stopped operating, what difference can a low flow rate make?
