Problems solved by technology

[0006] First, it is impossible to effectively judge whether there is gas residue in each part of the furnace, and the ignition is easy to cause flash explosion and cause personal injury
[0007] The second is that the heating furnace models are different, and the size of the ignition hole is different (the size of the ignition hole on site is: 35mm, 40mm, 45mm, 80mm). When the ignition gun is in use, it cannot be effectively fixed. In the hole, there is a problem that it cannot be ignited effectively and the ignition gun is easily damaged
Although the process of processing the ignition gun bracket and fixing the ignition gun has been studied on the spot, there is a shortage of increasing the operation process
[0008] Third, the remote control of the ignition gun is easy to run out of power, be damaged, or lost, making the ignition gun unusable
[0009] Fourth, the ignition gun has a large volume and is inconvenient to carry. Affected by the location of the well and the station, the water jacket heating furnace is widely distributed, which increases the labor intensity of the employees.
At the same time, because the ignition gun is inconvenient to carry, some employees have illegal operations and use torches to ignite. When people use torches to ignite, they are close to the ignition hole. If there is residual gas in the furnace, it is easy to cause flash explosion and hurt people.

Abstract

The invention provides a spontaneous-combustion igniting agent. The igniting agent contains a first system and a second system, wherein the first system contains an oxidizer; and the second system contains a reducing agent, a combusting agent and a packaging agent. According to the spontaneous-combustion igniting agent, heat can be released through oxidation-reduction reaction so as to generate combustion; and the spontaneous-combustion igniting agent has the advantages that delayed spontaneous ignition is realized, the delay time can be controlled, and the combustion time is long.

Description

technical field [0001] The invention relates to a self-igniting igniter, in particular to a controllable time-delayed self-igniting chemical igniter. Background technique [0002] The heating furnace used in the oil and gas field industry can be called the oil field heating furnace. It is the most widely used oil field special equipment in the oil field gathering and transportation system. From the oil production wellhead to the crude oil transportation, the entire gathering and transportation system must use heating. furnace. As one of the most commonly used heating furnaces in oil fields, water jacket heating furnaces are used more and more as a large area enters a high water cut period and heavy oil and natural gas development. [0003] The water jacket heating furnace mainly ignites the combustible gas, so that the combustible gas can continue to burn in the furnace, so as to heat water, oil-water mixture, and oil-gas-water mixture, reduce the viscosity of crude oil, an...
