Next Level Efficiency – Take your plant to the next level

Many companies with highly efficient core equipment, such as tunnel washers in the laundry industry, look for additional ways of saving energy. One well-established method is heat recovery from the plant process. Gas heat reclaimers have been used in industrial plants for decades preheating water for plant operations. It was not uncommon for old technology, with limited heat recovery capacity, to develop mechanical and corrosion problems. Over the years these weaknesses have been virtually eliminated. Today’s modern stack economizer has improved significantly in terms of efficiency and application and for over 50 years, Kemco has been at the forefront of this technological development.

The most efficient system in the market for flue gas heat recovery is the direct contact stack economizer. The stack economizer takes energy that would normally be sent out the exhaust stack and uses it to heat incoming water for process. By recovering this waste heat, a stack economizer can reduce fuel requirements resulting in high long-term savings and a fast return on investment (ROI). ROI’s can run as high as 100% per year and returns over 50% per year are common. The amount of recoverable heat using stack economizers depends on several factors, including initial stack gas temperature and firing rate. In general, boiler efficiency can be increased by 1% for every 40°F reduction in flue gas temperature. For instance, a 400hp stack economizer is able to recover 65% of the heat which would be otherwise be wasted. This could translate to annual energy savings between $31,000 and $60,000.

Overall the addition of a stack economizer is one of the most profitable investments to boost plant efficiency. Kemco’s stack economizers use stainless steel materials on all major parts to ensure durability and reliability and are built to last, requiring minimal maintenance over its lifetime. Today thousands of companies across different industries, such as laundry and food processing, rely on stack economizers to get the maximum out of their energy spending. Are you ready to join them with a Kemco stack economizer?
