Description

one

The invention relates to the heating of natural gas in main pipelines, namely, to heat generators for heating the stop valves of pipelines and compressor stations designed to prevent the formation of gas hydrate plugs.

The purpose of the invention is to reduce operating costs at startup.

The drawing shows the scheme of the proposed heat generator, where a, b. - from -, boron lines, in - air supply; g - the output of combustion products.

The heat generator contains a container 1 and Hozhukh 2 fixed on it with a heating device, which is made as attached to the vessel 1 and installed with a gap relative to the inner wall of the casing 2 of the perforated tray 3 with a pipe 4 for discharging combustion products having the form of a vessel on which The catalyst is 5, and electric heaters 6 placed in the gap, while the casing 2 is provided with a pipe 7 for supplying the gas-air mixture located concentrically outside the pipe 4 for removal of combustion products. The pipe 4 is made with a thermal compensator 8 and the pipe 7 is made with nozzles 9.

The heat generator works as follows.

Part of the gas from the main stream to line A is fed in mixture with air through pipes 9 to electric heaters 6. The heated gas through a perforated pan enters the catalyst 5. Combustion products are removed through pipe 4. At the same time, the heat of combustion of natural gas is transferred through the wall of this pipe baseline ha

zovozdushns th mixture, flowing through .tube space in the heat generator. After the operation of the catalyst goes to automatic mode (combustion on the catalyst is maintained by the heat of the combustion products of the initial mixture), a portion of the gas is removed after the valve (heated gas is removed). Such a technique further enhances the gas utilization ratio. After the output of the heat generator to the automatic mode (50-60 minutes), the electric heater is disconnected. In this case, thermal overload inside the heat generator is removed using a thermocompressor. Such a technique allows catalytic combustion in automatic mode with large temperature differences of the initial gas-air mixture.
