Indonesia's household chemical market is undergoing structural changes as the largest country in Southeast Asia with a population of 280 million. With the strengthening of cleaning habits by the middle class and religious culture, categories such as laundry products and personal care have a compound annual growth rate of over 5%. All need continuous and stable high-temperature steam support during the core links in household chemical production such as saponification reaction, essence extraction, filling and sterilization. The protagonist of this case is a large household chemical plant in Indonesia. The traditional coal-fired boiler of the enterprise had serious problems of exceeding pollutant standards and were facing urgent pressure for rectification although it’s  with the characteristics of low cost. It would not only cause serious pollution to the surrounding environment, but also made the enterprise face high fines, production suspension for rectification and other penalties if rectification is not carried out. Although a single gas boiler performs well in terms of pollutant emissions, it also has a shortcoming of being prone to shutdown risks when natural gas supply is unstable. If natural gas supply is tight and pressure is insufficient during the winter gas peak period, gas boilers cannot run normally, and the production of the household chemical plant will stagnate,which cause huge economic losses to the enterprise. So, the company urgently needs a heating equipment that can balance efficiency, cleanliness, and fuel flexibility to meet the dual needs of production and environmental protection. This household chemical plant finally chose Xinli Boiler's WNS series oil gas fired steam boiler as their steam supply equipment after conducting in-depth research and technical evaluation on numerous boiler products in the market.

This WNS series dual fuels fired steam boiler from Xinli Boiler features a dual fuel burner with German technology that seamlessly switches between natural gas and diesel. It monitors the fuel supply status in real-time through an advanced PLC control system. When the natural gas pressure is insufficient, it can automatically switch to diesel mode in a very short time of less than 30 seconds that ensure the continuity of steam supply and avoiding production interruptions. It can effectively avoid product quality problems and production delays caused by insufficient steam supply to reduce potential economic losses for the enterprise. Whether it is the economic operation when there is sufficient natural gas supply or switching to diesel mode when there is a problem with natural gas supply, it can ensure 24-hour continuous gasoline demand for daily chemical plants and avoid production stagnation caused by fuel issues. In terms of environmental protection and energy conservation, the boiler is equipped with internationally renowned low nitrogen burners with a combustion efficiency of over 98%, which can fully burn the fuel and reduce energy waste. At the same time, NOx emission of the boiler is less than 30mg/m ³ that can meet the strictest international environmental standards to help the factory easily cope with environmental regulatory pressures and avoid penalties for non-compliance with environmental standards. The successful application of this 8-ton WNS series oil gas fired steam boiler in an Indonesian household chemical plant has strongly demonstrated its reliability and economy under complex working conditions.
