Swiss Waste to Energy Plant to be Retrofitted with HZI Combustion & Bottom Ash Technology

Swiss waste to energy equipment manufacturer, Hitachi Zosen Inova (HZI) has signed a contract with Horgen, Switzerland based waste management firm, ZVHo to retrofit new bottom ash and combustion technologies to its KVA Horgen waste to energy facility. According to HZI the deal will secure the operation of the plant through to 2030. The company explained that while slag from incineration was previously quenched and discharged in wet form, KVA Horgen will instead feature dry bottom ash discharge. The aim is to process the bottom ash at ZAV Recycling in Hinwil, to increase the recovery of valuable mineral and metal materials, and thus deliver a sustainable environmental benefit. According to HZI its technologies will enable the bottom ash discharge to not only be dry, but also completely dust-free. In addition to the modernisation of the existing boiler and flue gas treatment system, a new incineration system will also be installed at the plant, which HZI said is the first time that this system has been retrofitted for industrial application. It was said that this will reduce the long-term maintenance costs while at the same time increasing energy efficiency. The company said that the furnace it has developed produces less CO, raw NOx, and fly ash. The combination of the new dry scrubbing flue gas treatment system Xerosorp+ and a heat exchanger to recover thermal energy is also expected to enhance the economic efficiency of KVA Horgen. HZI claimed that its Xerosorp+ process ensures exceptionally low emissions of harmful substances, and delivers decisive energy savings since the treatment system functions without the energy intensive reheating usually used prior to the catalyst. According to the company a new heat exchanger at the waste to energy plant will also mean much more energy can be recovered from the flue gases. This new process is said to make a two-fold contribution to ensuring that the treatment of our daily waste is as environmentally friendly as possible. At the same time, HZI said that the requirements of the Swiss Ordinance of Air Pollution Control are met within the smallest possible building volume. The contract is said to be worth more than CHF 13 million ($13.5 million). The retrofitting work will commence in April 2015, and is expected to be completed in good time for the start of the heating period in the fall of 2015.
