Energy saving safety control device of oil field gas heating-furnace

The utility model discloses an energy-saving and safety control device of gas furnace in the oilfield for petroleum industry, and is suitable for the oil production wells used in heating and transportation of the crude oil by the gas furnace. The device comprises a safety valve. The natural gas is introduced into the bottom of the furnace body for combustion through a feed piping and a control valve, and on the feed piping is equipped with a gas control system. The controller is communicated with an oil temperature sensor, a water temperature sensor and the gas control system by cables. The utility model solves many problems including no precise control of oil discharge temperature, burnt furnace, poor security and waste of energy of existing heating system of the gas furnace during the transportation of the crude oil in the oilfield, so as to achieve the purposes of protection of equipment and safe production.
