Steam Purity. Boiler pressure plays an important part in mechanical carryover, as the density of water and steam approach unity as the pressure approaches the critical point of 3208 psia. With vaporous carryover, the impurities volatilize, and are not entrained in moisture droplets as they enter the steam.

Water or steam injection can reduce NOx up to 80% (when firing natural gas) and can result in lower reductions when firing oils. There is a practical limit to the amount of water or steam that can be injected into the flame before condensation problems are experienced.
In addition, by piping the boilers in a primary/secondary system, no water will flow through an “off” boiler, reducing heat losses through the stack and boiler jacket of the off boiler. It’s as if the off boiler were valved off from the rest of the system, even though it isn’t.
In low-pressure boilers, mechanical carryover (the entrainment of boiler water in the steam) can be caused by a high concentration of dissolved solids in the boiler water, resulting in surface tension reduction and boiler water destabilization, and potential foaming in the steam drum.
(boiler) and secondary (system) loops –Closely spaced tees or a mixing manifold • Prevents flow in one circuit from interfering with another –Example: As zone valves open, close, or modulate, and as system pumps vary speed, the boiler loop is not impacted.

Time Delay Relay (For Hot Water Boilers Only) When the thermostat clicks on, the relay causes the boiler to circulate hot water through the system without turning on the boiler. After a set time, the boiler will fire up. A time delay relay costs about $100 and can cut your fuel costs by up to 10%.
There are two main ways burner manufacturers have accomplished this without post-combustion control: steam injection and flue-gas recirculation (FGR). Steam injection—injecting steam into a flame—works because steam temperature is considerably lower than flame temperature—in the case of a boiler operating at 300 psig, 421°F vs. 2,400°F
Flue Gas Desulphurization The addition of hot water to a lime slaker can help improve and reduce the reaction time thus saving costs by reducing the amount of lime used. The installation of a PSX Direct Steam Injection Heating System improves performance as well as
Ammonia injection; Flue gas desulphurization (FGD) Designing boilers with higher exit gas temperature reduces the boiler efficiency. As a rule of thumb approximately every 20 degree centigrade increase of flue gas temperature at boiler outlet reduces the efficiency by 1%. Hence this is not a preferred method in the present days.
Water/Steam Injection. Water or steam injection can be utilized to reduce NOx levels. By injecting water or steam into the flame, flame temperatures are reduced, thereby lowering thermal NOx formation and overall NOx levels. Water or steam injection can reduce NOx up to 80% (when firing natural gas) and can result in lower reductions when firing oils.
