Discussion on Design Principles for Waste Heat Recovery Steam Balance in a Sulphur-Burning Sulphuric Acid Plant

Steam balance is the key for the design of waste heat recovery system in a sulphur-burning sulphuric acid plant.Its reasonable design has direct influence on the economic benefit of the enterprise.The issues to be considered during the steam balance design are outlined,such as the plant capacity,plant steam source and user,steam use and associated facility,low temperature heat recovery,provision of auxiliary boiler,selection of steam parameters,determination of steam pipe network,as well as utilization of energy-saving equipment,and recovery of condensate,and the necessity of properly solving these issues is pointed out.
