They power package boilers, start up larger furnaces with fluidized beds and grates, and heat many other processes. Larger burners have Combustion Control Systems (CCSs) which should be tuned periodically. To understand how to tune a gas and/or oil (usually #2 Diesel oil) burner, it helps to first understand how and why they work the way they do.

However, much of that savings can be attributed to a more reasonable manual tuning of the boiler, and not necessarily from the installation of an automatic O2 control system. Well-tuned boilers can expect savings of 2 – 4% according to Hays Cleveland. Estimating Payback from the Installation of O2 Trim
Blowdown controls the buildup of solids in the boiler water; it protects the boiler’s surfaces, enhances heat transfer, and ensures a safe chemical concentration. Unfortunately, blowdown often is either neglected or overused during routine maintenance. Optimizing blowdown performance reduces energy use. Make sure blowdown is at the

near the boiler or junction box. Then put the Heat Link cover back on. To help ensure a good wireless connection to the thermostat: • Leave at least 30 cm of space on each side. • Install it within 30 m of the thermostat. Boiler Heat Link Thermostat 30 cm min. 30 m max.
The boiler water or blowdown must therefore be evacuated either continuously or at intervals. This is the task of the BAE valves. Their wear-resistant nozzle stem has a special geometry, whereby the needle is centrally located when it enters the system of nestling expansion chambers.
In this type of system the feedpump runs continuously, and an automatic valve (between the feedpump and the boiler) controls the feedwater flowrate to match the steam demand. When operating correctly, modulating control can dramatically smooth the steam flowrate chart and ensure greater water level stability inside the boiler.
The Basics of Tuning PID Loops Chris Hardy | April 9th, 2014 The art of tuning a PID loop is to have it adjust its OP to move the PV as quickly as possible to the SP ( responsive ), minimize overshoot , and then hold the PV steady at the SP without excessive OP changes ( stable ).
Reusing hot condensate in boilers saves energy, reduces the need for treated boiler feed water and reclaims water at up to 212 degrees Fahrenheit of sensible heat. Improve Boiler System Operations Operating the boiler system at the proper steam pressure can save energy by reducing stack temperature and leaks in steam traps.
