Experimental investigation of coil type steam generator performance when used in North oil fields

Transportable boiler plant, widespread in the Northern regions Russia, is used in various fields. The equipment currently in-use, as well as the existing boiler plants schemes have grown out of date and require either replacement, or modernization. The new plant features a coil type steam boiler and ancillary equipment, designed to mitigate the identified limitations. Steam boiler coils are coaxial cylinders. The modernized transportable boiler plant is installed and used in an oil field in the North. The paper presents an experimental and theoretical research into the coil steam boiler actual performance. It also presents the boiler plant operation experimental data, the dependencies temperature and pressure of the coolant on the plant fuel consumption rate. The collected data has undergone statistical analysis. The authors present the conclusions, identifying the promising direction for further research and improvement of coil type steam boiler. The equations for the calculation of the convective component of radiant-convective heat transfer in flues are proposed. These equations account for the boiler unit design features, as new correction indices are introduced. When checked against the experimental data, the calculated data is proven to be satisfactory.
