Abstract
Apparatus for determining corrosion or deposition rate of corrosive constituents in the flue gases of a boiler system. A probe loop has a coolant circulating therethrough wherein the loop includes a removable specimen that can be tested for deposition or corrosion rate. The coolant recirculates through the loop to maintain the surface temperature of the specimen substantially constant approximating the maximum corrosion temperature. Coolant is fed to the probe loop by a coolant tank which includes a liquid coolant reservoir in a lower portion thereof and a gas chamber for gaseous coolant in an upper portion thereof. The gas pressure within the gas chamber can be varied so as to vary the boiling point temperature of the liquid coolant. The gas chamber is connected to the lower end of a condenser coil which has a variable heat transfer area. Between the gas chamber and the condenser coil is located a contact bed to enhance the contact of condensed coolant and gaseous coolant. To enhance the flow of the coolant through the loop by nucleate boiling the return run and supply runs of the loop are inclined upwardly.
