Abstract: Since the 1990s, regenerative flue gas waste heat recovery unit of high temperature air combustion technology was used widely in the steel, iron, glass and molten aluminum industry. But the application on the vapor injection boiler in oil field was rarely reported. The principle of the regenerative combustion technology was introduced. Fuel efficiency, energy saving rate and steam production mass rate of the steam injection boiler were respectively calculated under the condition of the same fuel, furnace, furnace outlet smoke temperature using the conventional combustion technology and regenerative combustion technology. The results show that after applying the regenerative combustion technology, the boiler could not only save energy and improve fuel efficiency, but also improve the steam production mass rate. At the same time, it also could realize the use of lowergrade fuels. According to the characteristics of steam injection boiler, regenerative combustion technology could be completely applied to the steam injection boiler.
