Torch burning surface protection flame stabilizing device and underwater transfer torch

Abstract

The invention provides a torch burning surface protection flame stabilizing device and an underwater transfer torch, the burning surface protection flame stabilizing device is arranged at the upper part of a burning surface of torch fuel, a relatively closed stable area is formed between the burning surface protection flame stabilizing device and the burning surface, and full protection or local protection is formed on the burning surface. A torch combustion surface covering bowl combustion technology is adopted, the whole or partial combustion surface of underwater torch fuel is protected, one of an oxidizing agent type fuel, a double-base explosive type fuel and a composite explosive type fuel is adopted, smokeless and less-smoke combustion is achieved through environment pressure combustion, the spark splashing phenomenon is eliminated, the weight is reduced, meanwhile, safety is guaranteed, and the environment protection effect is achieved. And underwater reliable ignition and continuous and stable combustion are realized.

Description

technical field [0001] The invention relates to the technical field of stable combustion of solid fuel torches, in particular to a flame-stabilizing device for protecting the burning surface of a torch and an underwater torch transfer. Background technique [0002] Relaying the torch is an important activity, and so far, the torch has been carried out in the atmosphere, at high altitudes, underwater, and in extremely cold and hot areas. The torch relay adopts a solid pyrotechnic powder scheme, and has a corresponding combustion system invention patent, publication number CN101033856A, which involves technologies related to solid fuel and slurry composite fuel. [0003] The torch uses propane gas, butane gas and oxygen to form a combustion system, and completes the torch relay ignition underwater. Among them, the underwater torch burns to produce a large amount of white smoke and sparks characteristic of metal fuel. Obviously, a pyrotechnic fuel system is used. Propane gas, ...

AI Technical Summary

Problems solved by technology

However, the main problems of the two existing underwater torch transfers are that the burning time of the torch is too short, the smoke of pyrotechnic fuel is too large, and the safety issues of pressurized combustion

If the time is too short, it is not conducive to carrying out necessary activities, the smoke is too large to meet the concept of environmental protection, and the flying sparks may easily cause safety hazards

In addition, there is a long tube protruding from the head of the torch when the torch burns, which affects the appearance

However, other solid fuels than AP / HTPB and double-base drug solid fuels are environmentally friendly and have beautiful flames, but they are difficult to ignite and burn underwater, and cannot maintain combustion.
