I have a question: the process requires 5 t/h of steam, so a 10 t/h boiler was installed. How does this boiler operate? Thank you!
The excess energy can be used to power the pumps in the factory, and the boiler can operate stably at at least 70% load. In short, it’s easy to make use of even a few tons of such energy; if that doesn’t work, ask your supervisors to set up a bathhouse in the factory for you~~~
Add a heat exchanger to heat the water. . It’s up to you to decide how to use the hot water – it can be used for heating as well as for sanitary purposes
It is not cost-effective to operate a boiler at too low a load; generally, a combustion load of 80% is considered optimal. I’ve never encountered a situation where your performance is below this economic indicator value. However, in the past, when we used boilers, we usually had a set of steam reciprocating pumps available for emergency use, to supply water to the boiler in case of a sudden power outage that lasted for an extended period. This might be useful as a reference for you: by using the excess steam to supply water to the boiler, it would be necessary to add another steam reciprocating pump. I’m not sure if any companies are still using this approach these days, and I wonder how the economic efficiency of steam-driven pumps compares to that of electric multi-stage pumps
Your company’s situation is similar to that of our organization before. Ours uses 6 tons of steam for a 10-ton furnace. The boiler is not efficient. The theoretical calculation should be around 60. There is no other way. Later, the only option was to focus on energy conservation. Several frequency converters were installed. Water pump, blower, exhaust fan.
OP, in this case, a heat accumulator needs to be added. A instant noodle factory needs a boiler; the situation is similar to yours. With a heat accumulator, the boiler only needs to operate for half the time, while being shut down for the other half; the steam stored in the accumulator is used to keep the subsequent processes running. Of course, there are bathhouses at the supply factory, and the factory canteen is also excellent, helping to improve the quality of life for the employees.
What boiler? Fuel or coal? Just reduce the coal feeding rate for burning coal to a slower pace, that should do it, right?
The excess gas can be used for heating, bathing, cooking, and more – there are many ways it can be utilized. Since you use such large boilers, you must have a considerable number of employees. Using a steam regenerator is also a good option.
Will this work? Can the boiler’s load be adjusted to 50%?
In that case, the usage rate is really low. But it can be used for heating.
Using a regenerator is a good approach. However, the parameters of the regenerator mainly relate to whether the steam at the outlet can meet the requirements of the user’s process
Going back to floor 9, although controlling the boiler efficiency at 50% can meet your requirements, such a low efficiency is not desirable. . You’d better follow the suggestions given by others and keep it at 70-80%; make use of any excess as much as possible!
