Walsn Enterprises Ltd.
The fuels used in boilers, such as coal, heavy oil and natural gas, contains S. during the combustion process, S and O₂ form SO₂, and a small amount of SO₂ is converted into SO₃ under catalysis of Fe₂O₃, V₂O₅ and other catalysts. Under normal circumstances, the volume of SO₃ in the boiler flue gas is 1×10-6～50×10-6, and the water vapor is about 10%. When the temperature of the flue gas is below 200°C, SO₃ and the water vapor are completely combined into H₂SO₄ vapor. A small amount of H₂SO4 vapor will significantly increases the acid dew point. When the surface temperature of the boiler heat exchange equipment is lower than the flue gas acid dew point, the H₂SO₄ vapor will condense on the surface to become sulfuric acid solution with a concentration of about 80%, which will adhere to the surface of the heat exchanger and cause acid corrosion. Typical equipment that is prone to corrosion includes air preheaters, induced draft fans and flue walls.

General Tools & Instruments
All psychrometers derive an environment's wet-bulb and dew point temperatures from a precise measurement of relative humidity. The original psychrometer had two thermometers mounted together with a handle attached on a chain. One thermometer was ordinary. The other had a cloth wick over its bulb and was called a wet-bulb. New, digital versionslike General's EP870X family improve on this basic design, offer HVAC technicians a better tool for recharging the refrigerant of a residential or commercial A/C system.
