Boiler Controls

Significant developments have taken place in recent years improving considerably the standards of safety and reliability of boiler level controls. Probes without moving parts and modern electronic solid state controllers are so reliable that major boiler accidents should be a thing of the past.

By measuring the TDS level in the boiler water, Spirax Sarco has developed boiler blowdown systems that will minimize the amount of blowdown required, reduce carryover of boiler water and provide automatic TDS control. The Spirax Sarco CCD condensate contamination detection system monitors the conductivity of condensate being returned to the boiler. Contaminated condensate is diverted to drain thereby protecting the boiler.

Spirax Sarco vent heads are designed for fitting to vertical open-ended steam vent pipes. The vent head incorporates an internal baffle which separates entrained water from the steam, safely discharging dry steam at decreased velocity to atmosphere, protecting personnel from injury, buildings from damage and minimizing the nuisance of water spray. Simple and effective vent heads for increased safety and environmental protection.

The Spirax Sarco key operated blowdown valve is designed for the manual blowdown of steam boilers to remove precipitated solids from the bottom of the boiler.
