Conical spring type high efficiency energy-saving furnace and using method thereof

Abstract

The invention relates to a conical spring type high efficiency energy-saving furnace and a using method thereof. The technical scheme lies in that the conical spring type high efficiency energy-saving furnace comprises a chimney, lifting rings, a housing, a flange, a furnace shell, an annular support, an igniter, a gas burner, a ventilating board and an air door, wherein the top of the furnace shell is connected with the housing through the flange and bolts; the middle at the top of the housing is communicated with the chimney; the two lifting rings are arranged on the upper end surface of the housing in a symmetric manner; the annular support is arranged in the furnace shell; a conical spring heating coil is fixed on the annular support; the igniter and the gas burner are arranged at the lower part of the annular support; the igniter is positioned at the upper part of the gas burner; the inlet and the outlet of the conical spring heating coil extend out of the furnace shell; the gas burner is fixed on the ventilating board in the furnace shell; ventilation holes are formed in the ventilating board; the air door is arranged on one side of the bottom of the furnace shell. The conical spring type high efficiency energy-saving furnace and the using method thereof have the benefits as follows: a cylindrical steel structure is adopted, the furnace body is small in size, and the gas consumption is low; besides, the heating coil takes the shape of a conical spring, the heating points are concentrated, the heating coil is free from welding points, and the heat efficiency is high.

Description

technical field [0001] The invention relates to crude oil transportation and wellhead heating in the petroleum industry, in particular to a tower spring type high-efficiency energy-saving furnace and its use method. Background technique [0002] In the process of oil recovery and production, single well trunk heating furnace is an important heating facility in the process of oil well transportation. Under the influence of poor physical properties of crude oil and long oil pipelines, many oil wells need to heat the wellhead to reduce the viscosity of crude oil to achieve the purpose of normal oil delivery. At present, most oil wells use a single-well mainline heating furnace with a rectangular cement pouring structure. , because the main line furnace is straight-through heating and has a large internal space, under the normal air source, there will be a problem of large heat loss and slow heating during heating. It will cause a series of problems such as oil well back pressu...

Under the influence of poor physical properties of crude oil and long oil pipelines, many oil wells need to heat the wellhead to reduce the viscosity of crude oil to achieve the purpose of normal oil delivery. At present, most oil wells use a single-well mainline heating furnace with a rectangular cement pouring structure. , because the main line furnace is straight-through heating and has a large internal space, under the normal air source, there will be a problem of large heat loss and slow heating during heating. It will cause a series of problems such as oil well back pressure, high plugging pipeline, etc., which seriously affects the normal production of oil well.
