Chemical Reaction In A Diesel Boiler

What Are Diesel Emissions

Freedom from corrosion and chemical attack - If the water contains dissolved gases, particularly oxygen, corrosion of the boiler surfaces, piping and other equipment is likely to occur. If the pH value of the water is too low, the acidic solution will attack metal surfaces. If the pH value is too high, and the water is alkaline, other problems

The combustion process is an exothermic chemical reaction of the oxidation of hydrocarbons. In layman's terms, the oxygen in the air and the hydrogen and carbon in the fuel are oxidized (combined) in the combustion process and the result is heat and CO2 (carbon dioxide) and H2O (water vapor).

Introduction. Diesel engine, like other internal combustion engines, converts chemical energy contained in the fuel into mechanical power. Diesel fuel is a mixture of hydrocarbons which—during an ideal combustion process—would produce only carbon dioxide (CO 2) and water vapor (H 2 O). Indeed, diesel exhaust gases are primarily composed of

high pressure combustion – Industrial Boiler

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil.

Chemicals used for this purpose are called oxygen scavengers, the most commonly-used of which is sodium sulfite. Sodium sulfite reacts with feedwater dissolved oxygen to form sodium sulfate, an innocuous salt that is removed in the blowdown. Sodium sulfite is available as a powder or as an aqueous solution.
