With their highly volatile and flammable fuels, gas engines require extensive measures to prevent and counter the effects of unintended explosions outside the combustion chamber. Hoerbiger Ventilwerke has developed a method capable of rapidly determining the optimum number and position of explosion relief valves in intake and exhaust systems.

Explosion protection on gas engines

Large spark-ignited gas and dual-fuel engines need to be protected against explosions in their inlet and exhaust systems. Compared to crankcase explosions, these events are harder to model, and there are no accepted standards for sizing and locating relief valves. Design methods based on 3-D Computational Fluid Dynamics (CFD) models are slow, expensive, and of unproven accuracy. A new approach based on 1-D modelling, on the other hand, is low cost, easy to use and matches experimental results well. By helping engineers to optimise relief systems, the new software makes engine system design safer, quicker, and...
