combustion in gas boiler Agents - mantrasphere.co.uk

Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

The water is confined by the outer shell of the boiler. To avoid the need for a thick outer shell, fire tube boilers are used for lower-pressure applications. Firetube boilers can be sub divided into three groups. Horizontal return tubular (HRT) boilers typically have horizontal, self-contained firetubes with a separate combustion chamber.

Maintaining the pH of boiler water in the range of 9–11 decreases the rate of corrosion; 9.2 to 9.8 is ideal. In low-pressure steam or hot water heating systems, nitrite or chromate provides a protective film on metal surfaces. Filming amines provide a physical barrier to protect metal from corrosion. They are effective in the pH range of 5.5
