Injection Versus 4-Way Valves - PM Engineer

Sep 30, 2002 · The faster the injection pump runs, the faster hot water is injected into the distribution system, the warmer it gets, and the greater its heat output. As with 4-way mixing valves, the controller operating the injection pump must also sense boiler inlet temperature to protect the boiler from condensing mode operation.

Homemade Water Injection for Auto Engines | It Still Runs

Water/Meth Injection Basics. As the mix of water, methanol, air and gasoline enter the piston, the heat created from compression vaporizes the water rather than heating up the cylinder walls. The methanol burns like gasoline, but does so at higher pressures, so the effective octane of the gasoline is increased.

Myths and methods for protecting boilers against flue gas

Nov 27, 2017 · The presence or absence of sustained flue gas condensation is determined by the temperature of the water entering the boiler and the air/fuel ratio at which combustion occurs. Of these, only the boiler inlet water temperature is easily controllable by how the boiler is applied.

Water Injection for NOx Reduction | GE Power Generation

For non-Dry Low Emissions (DLE) turbines without a NOx abatement system, a water injection system can be added that lowers NOx emissions to 25 ppm (gas fuel) or 42 ppm (liquid fuel). This system injects demineralized water into the combustor through the fuel nozzles to regulate the combustor flame temperature and lower NOx emissions.

Boiler Combustion | CleanBoiler.org

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.
