Which type of boiler can burn both oil and ethylene off-gases?
Thread Content
During our company’s production process (which is batch-based), ethylene off-gases are generated, and these are currently burned using a flare system. It is neither environmentally friendly nor energy-efficient. If there is any boiler manufacturer that can design a small boiler (2-3 t/h of steam) capable of burning both diesel and ethylene off-gases, please contact us via email at ali2277@163.com. Thank you for your cooperation.
The boilers manufactured by our company should work fine; it mainly depends on whether the burner is suitable for burning ethylene gas. Currently, there are burners available on the market that can use both oil and gas, but most of them burn natural gas or associated gas.
Most conventional oil and gas boilers will suffice. As mentioned above, the choice of fuel depends mainly on the burner; it is advisable to have information on the composition of the gas and its calorific value, so as to select the appropriate burner.
The issue you mentioned is commonly referred to in engineering as converting a boiler from oil to gas or mixing gas with oil. We have been working on projects related to the conversion of boilers from oil to gas recently. In 2008, we converted several boilers, including those with a capacity of 170T in Maoming, 165T and 70T at Yanhua, and 160T at Yangzi. Currently, we are working on the conversion project for a 65T boiler at Jihua. Generally, boilers should be able to burn both oil and gas; all that’s needed is to replace the burner. However, a key issue is that when burning gas, the radiant heat transfer in the furnace decreases compared to burning oil, while the convective heat transfer increases, which may lead to overheating of the superheater. This requires re-evaluating the structure and parameters of the boiler; therefore, it is not certain for each boiler whether it can use gas in its combustion process, or how much gas can be used. If you would like to discuss further, you can email me at zhangf@calt11.cn to explore this together.
Agree with what was said above; most companies will work fine, it just requires some minor adjustments
Primarily, it’s the stability of the gas supply. Consider the explosion-proof requirements and other factors, as well as the associated costs and downtime. Delivering gas to the boiler room isn’t something that can be taken lightly – all motors need to be explosion-proof, and there are also gas detectors required….
