Ultra High Pressure

Transitional fire attack the PyroLance way

The fundamentals of PyroLance technology have been known to the fire service for almost one hundred and fifty years according to Cas Seyffert, PyroLance VP of Operations. He quotes an 1866 statement made by James Braidwood, Chief Fire Officer of the London Fire Brigade. “The men of the fire brigade were taught to prevent, as much as possible, the access of air to the burning materials.  What the open door of the ash-pit is to the furnace of a steam boiler the open street door is to the house on fire. In both cases the door gives vital air to the flames.”5

Let’s start with water. Water possesses the greatest practical specific heat capacity of all naturally occurring substances and has the greatest latent heat of vaporization of all liquids. The latent heat of vaporization is the amount of heat required to change a liquid into a vapor without a change in temperature

Ultra high pressure water mist systems operate on the principle of generating very fine droplets of water and delivering them to the fire zone.

The advantage of this is that water mist can be very effective at fire suppression due to its high specific heat and heat of vaporization coupled with the increased surface area allowing faster heat absorption.

When discussing water mist systems, often the immediate interest is in the droplet size of the water particles being produced as this factor greatly effects how the spray will interact with the fire and which of the extinguishment mechanisms listed above will play significant roles.

The size of water particles plays an important part in the characteristics and interaction with a fire. In the case of heat extraction smaller particles result in a higher surface area and hence faster heat extraction for a given volume.
