Improvement of Economy and Environmental Protection for Heaters Used in Oilfield Gathering System by Condensation Technique

The heat efficiency of heaters used in oilfields is usually on the low side. Heat loss of exhaust gas is a major factor affecting heat efficiency of heaters. This paper outlines the current domestic status of heater technology and its shortcomings, discusses the principle, technical feasibility, economy and environmental protection, probes into the major factors affecting heat efficiency of condensation heaters. The analysis shows that the condensation technique enables the heat efficiency of heater to raise over 10% more than the o-riginal level, at the same time reduce the amounts of discharged harmful gases such as CO2, NOx, SOx . Therefore it is necessary to enhance the research work of condensation heaters and apply its results to production.
