"BIR-M" ignition unit

 Upgraded BIR-M ignition unit

Purpose

Spark ignition of pilot burners for gas consuming plants with gas pressure of up to 0.8 kgf/cm2 (80 kPa) and thermal power up to 5 MW.

It functions in manual mode and within automated systems.

Climatic version U (moderate), location category 1 (outdoor) as per GOST 15150-69, but for temperature range from -50°С to +50°С.

Description

BIR-M is an electronic unit enclosed in a metal body with a cover. The electronic unit is a board with point-to-point wiring, a high voltage transformer and capacitors. The power circuit and the discharger (igniter) circuit input cables pass through the glands located in the bottom part of the unit. The high voltage cable of the discharger (igniter) circuit is enclosed in a metal hose.
