The Development of Packaged Oil-fired Hot Water Heater

The packaged oil-fired hot water heater has been developed by Huadong Oil & Gas Transportation Administration Bureau and Oil & Gas Pipeline Survey and Design Institute of China. This new heater overcomes some shortcomings, such as cumber structure, backward technology and high energy consumption existed in the old-type heaters. The heater uses the double spiral tubes as its heated surf ace, which allows the hot water in the tube to flow to pass through the overall surface. Some new technologies and materials have been adopted for the new heater, such as pneumatic atomizing burner, micro-positive pressure burning, program-controlled start-up and lightweight heater wall fabricated with alumina silicate fibre. The heater has many advantages of high thermal efficiency, pet volume, light weight, fast start-up, simple operation, high safety and reliability and a long service life. Two winters' preliminary operation in Changqing pump station in LuNing pipeline shows that the technological parameters meets the requirements of the design.
