my no.2 question was that how we will come to know that what percentage of continuous blow down (c.b.d.)valve we should open so that we may keep concentration of dissolved solid in boiler water within limits. you know that there is a scale fitted on c.b.d. valve which shows opening of c.b.d. valve in percentage. (simply i want to ask you , is there any formula that can tell us what percentage of c.b.d. valve we will need to open to control the t.d.s. of boiler water. as a friend has already suggested that it can be adjusted on the basis of c.c. i want to know how we will adjust c.b.d.)
thanks.
