For the double-tank system, a two-step adjustment method was applied. The results showed that the single tank system will deteriorate the reliability of water heating for demand change condition, though it can reduce the oscillation of the output temperature. For the demand change condition, the regulation strategy was carried out based on the criterion of heat power equilibrium. And the improvement is highly related to the capacity of hot water tank.

The results showed that the application of water tanks can reduce the standard deviation of output temperature by 68.49% and 68.81% under the standard design condition, respectively. And two different working conditions were analyzed: (i) standard design condition, and (ii) demand change conditions. Two different strategies were thus considered: (i) single tank system, and (ii) double-tank system. The effects of water tank on the quality of output temperature was considered. In this work a simulation work was done to regulate the output temperature in a novel water heating system using solid graphite as thermal energy storage medium. Quality: ASTM Gr.45-12 (normalized and tempered)- 3,5%C 2,6%Si.The quality of output temperature is one of the key parameters for the reliability of water heating system. Possibility of safely making hard chrome plate on cast iron rolls fi 400mm.

Another important factor is to process as soon as possible after grit blast (before the metal oxidizes too much). (We use welding cable as temporary jumpers when going into tank live.) You will need to "strike" with about 6-8 amps/sq. "live", with both anode and cathode connected, and current on at about 6 volts. The problem was resolved by grit blasting as you mentioned, then going into the chrome tank We had similar problems plating chrome onto graphite cast iron, specifically meehanite gray cast iron. We are facing a problem while Hard Chrome Plating on Cast Irons containing Graphite, the chrome simply does not adhere, even afterģ.25 Amp/square inch.We are considering Grit Blasting or undercoat plating?
