Hello everyone! Today I’m going to share an amazing discovery about energy conservation, which may bring new energy benefits to your business! Let us explore the magic of small steam boilers together.
The boiler system of a medical center in Taiwan uses two 2.5 tons/hour steam boilers that have been used for more than 15 years, mainly operating on natural gas. However, in a test, we found that the oxygen content of one of the exhaust gases was as high as 7.5%, the exhaust gas temperature was as high as 170°C, and the boiler efficiency was only 64.5%. This kind of operating state is really amazing.
In order to improve this situation, we proposed an ingenious plan: add a small once-through steam boiler with a capacity of 500kg/hr, equipped with an economizer, and its combustion efficiency is as high as 90%! This not only reduces the frequency of starting and stopping large boilers, but also greatly improves combustion efficiency, making your energy use more efficient.
In order to better cope with the demand during peak hours, we recommend starting the old boiler during times of greater steam demand every day, and letting the small once-through steam boiler take over at other times. In this way, you can not only reduce the frequency of starting and stopping the boiler, but also increase the overall efficiency to 24.5%!
The expected benefits of this improvement program are considerable. The annual natural gas consumption saved reached 206,658 cubic meters, and the combustion efficiency increased by 24.5%, which is a contribution to environmental protection. Converted into money, the annual natural gas cost savings can reach 520,000 yuan! This is not only caring for the environment, but also a wise use of funds!
Taking into account the investment costs, the cost of adding a 500kg/hr small once-through boiler and economizer is about 780,000 yuan, but don’t worry, according to our evaluation, this investment will be recovered in just 1.5 years! This is definitely an energy-saving solution worth considering, charting a brighter path to energy efficiency for your business.
Small changes can bring huge benefits. Let’s dive into the world of small steam boilers and get a glimpse of their unique energy-saving magic!
