Improvement of the technology of flame arrester manufacturing
When mining hard coal the underground method is prevailed. This method provides a higher quality of the mineral. Methane emissions occur in coal mines during the development of gasbearing seams. These emissions are the reason for the formation of an explosive mixture when mixed with mine air, and...

| Summary: | When mining hard coal the underground method is prevailed.
This method provides a higher quality of the mineral. Methane
emissions occur in coal mines during the development of gasbearing seams. These emissions are the reason for the formation
of an explosive mixture when mixed with mine air, and also
contribute to the spontaneous combustion of coal. Methane
alarms are used to monitor the mine atmosphere. Thermocatalytic
sensor is the main element of such a gas analyzer. The sensor
is placed in a breathable housing. This body is called a flame
arrester. This article discusses the possibility of replacing the
material used for the manufacture of a flame arrester. The basis of
the existing material is nickel powder. It is proposed to replace it
with a cermet bond. The composition of the ceramic material of
the part is developed by the author and presented in the article.
Replacement of material will lead to a significant reduction in
the cost of the part and simplification of the manufacturing
technology. |
