The National : JAN FEB MARCH 2018 DRYCLEANER
24 THE AUSTRALIAN NATIONAL DRYCLEANER & LAUNDERER JANUARY FEBRUARY MARCH 2018 WASHERS AND DRYERS Duct work might be an 8” duct, but if you allow lint to build up it can narrow to 4” very quickly and then you don’t get the evacuation of water and steam as it is required. Air gets caught on lint and you get increased energy usage and costs. Be aware that the shock absorbers “shockies” can wear out and need replacing: there is an easy test. Push the machine away from you and if it comes back and wobbles, the shock absorbers are shot and need replacing. If it comes back and stops the shockies are still good. Regardless of how much stainless steel your washing machine contains, it may have panels or areas which are not stainless steel. These, if they come in contact with bleach, will develop rust spots. Don’t have a gas dryer near a perc machine or even where it will be drawing air from the perc machine area. Perc fumes will rot out your gas dryer, and fumes are bad for health. STEAM TRAPS Check all steam traps regularly, a very tiny leak out of a steam pipe will cost you money. You can prove easily whether your steam trap is working correctly, with just a drop or two of water. There is a pipe, and a steam trap and then more pipe. The inlet pipe should be hotter than the outlet pipe. So if you drop a couple of drops of water onto the inlet pipe it should sizzle. The job of the steam trap is to trap the steam condensate, so the other side, the outlet pipe, should not sizzle. There are other methods such as wax strips, stethoscopes, but a couple of drops of water will tell you if you have a problem. TDS If you have TDS for say four weeks, not a problem. In one case the water treatment guys were over zealous and affected the TDS too much. The fact is, without some TDS it will con- duct electricity very poorly. If you never blowdown your boiler you will have problems. Make it a rule to blow down in the morning, and again at the end of the day. Auto blowdowns are a great idea. THERMAL CONDUCTIVITY EXPERIMENT - PART 2 Daniel finished his address, and although the water had already been on the hot plate in excess of 25 minutes, it was still simmering and had not boiled. We decided to leave and go to dinner and for all I know it still hasn’t boiled. The thin layer of soil on the hotplate had the same insulating effect as scale does in your boiler: the water cannot heat up as quickly and therefore this wasted energy costs you more money every single day. Just 3 mls of scale will reduce the efficiency of your boiler by up to 20%. A gas boiler is only 80% efficient, while an electric boiler is nearly 100% efficient. If you take 20% efficiency away from a gas boiler, you are really in trouble. Old boilers, especially ones that have not been maintained, can be so inefficient that in fact it is more economical to replace them as the newer more efficient boilers will pay them off in reduced energy costs.
