Diesel Exhaust Gas

2020-1-22 · In addition to the physical properties, the exhaust system designer must know certain other exhaust gas parameters. These include exhaust gas temperature—which is of special importance for the design of catalytic aftertreatment devices, as catalyst performance is a function of temperature—and exhaust gas flow rate.

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%.

If you set it too high, as is possible if you use the first method and put the heating on full with an idea to turning it off soon after, the risk is that the water which returns to the condensing boiler after having circulated through the radiators will be too high a temperature to recover enough heat from the boiler’s exhaust gases.

As a result the temperature of the gases leaving the flue of a condensing boiler is typically 50-60°C compared with 120-180°C in a current non-condensing boiler. At the same time an

Air Fuel Ratio Effect on Combustion Efficiency

Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
