Steam generation issues in tubular furnaces
Thread Content
Dear colleagues, we use a methanol production process. Due to design constraints, the steam generated by our boiler in operation is only 12 t/h at a pressure of 25 kilograms per square centimeter, which is not sufficient to meet the production requirements. If we want to increase the steam output by another 15 t/h, is it possible to modify the existing tubular boiler so as to achieve a steam output of 27 t/h without having to build a new boiler? Our process for starting up the boiler involves the boiler water circulation pump transporting boiler water to the tubular furnace coils, from where it then goes to the steam drum to have steam separated out; the water in the steam drum subsequently returns to the boiler water circulation pump for further circulation. I would appreciate your advice.
Has the original poster’s problem been solved? What is the size of your tubular furnace? Is it possible to achieve a steam output of 12 T/H? It needs to be calculated. If you are interested, feel free to get in touch further.
The heat exchange surface area is too large, making renovation very difficult
