For an industrial steam boiler with a steam production capacity of 35 tons per hour, what desulfurization process is suitable?
Thread Content
For the desulfurization process of industrial steam boilers with a steam production capacity of 35 tons per hour, is the calcium oxide method used? Calcium hydroxide method? Between the above two processes, which one is better to use?
By using a double-layer turbine desulfurization tower and employing fly ash generated from coal powder combustion as the desulfurizing agent, SO2 emissions can be reduced to below 30 mg/Nm3.
A 35-ton boiler is considered a **phased-out small boiler**
May I ask: are you referring to the lime water desulfurization process? Is it the quicklime method? Still the slaked lime method?
35-ton small boiler； Simply spraying calcium into the furnace should be sufficient ； What is your sulfur dioxide level? ； Our 140-ton one ； All can be reduced below 100
The effect of calcium injection in the furnace is poor, and it is difficult to control.
The indicator we require is 200
(1) The desulfurization processes include the ammonia method, sodium method, calcium method, magnesium method, hydrogen peroxide method, etc.; the appropriate desulfurization process should be selected based on local conditions. (2) If calcium carbide slag is available, the by-product gypsum can be processed; the calcium-based desulfurization process is a good option, but the problem of scaling must be addressed. (3) I have just finished a desulfurization project; feel free to reach out to me.
Our 140 furnace； It also requires 200 ； Fully meets the standards ； The normal value is around 100
By the end of 2017, in the Beijing-Tianjin-Hebei region, coal-fired boilers with a capacity of 35 tons per hour or less were classified as **boilers to be phased out**. In other areas, it is 10 tons per hour for coal-fired boilers.
