Efficient water bath skid-mounted shale gas heating furnace and heating method

Abstract

The invention relates to a high-efficiency water-bath skid-mounted shale gas heating furnace and a heating method, comprising a heating furnace body and a torch in the furnace, one horizontal end of the furnace body is a fuel gas inlet end, and the other end is a shale gas pipeline interface end; A closed combustion torch is arranged in the lower half of the furnace cavity, and the furnace cavity outside the torch is a water-filled space; one end of the torch is connected to the combustion device, and the other end is connected to a smoke pipe extending in the opposite direction, and the smoke pipe is connected to the smoke box and the chimney in turn; At the gas inlet end, a combustion device is installed on the outside of the fire tube, and the fuel gas inlet pipe is connected to the ignition end of the combustion device; a horizontal internal combustion double-pass combustion structure is adopted, the fuel gas is heated along the fire tube in the forward direction, and then flows back along the smoke tube in the opposite direction. The heating effect is good and the thermal efficiency is high. At the same time, the layout of the smoke pipe and the torch is compact, and the volume of the furnace body is reduced; easy.

Description

technical field [0001] The invention relates to the technical field of petroleum engineering, in particular to a heating furnace and a heating method used in the oil and gas gathering and transportation process in shale gas development. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale and its interlayers, mainly in the form of adsorption or free. [0003] The water jacket heating furnace is one of the important equipment in the exploration and development of oil and gas fields. Due to the different physical parameters of oil and gas and the needs of the oil and gas gathering and transportation process, the heating methods and equipment used are not exactly the same. Therefore, the heating furnace used is difficult. Form a standard product. At present, similar products developed on the market include natural gas heating furnaces, split heating furnaces and vacuum phase change heating furnaces. There are still imp...
