The method to increase boiler efficiency is always a difficult problem for businesses. With many years of experience in the industry, KS Boiler will share with you the most effective solutions to improve boiler efficiency.
Causes of reduced boiler efficiency:
Types of boilers using fuel such as: Oil boilers, coal boilers, also known as wood-burning boilers, gas boilers, electric boilers… they are used in industry or in manufacturing establishments. retail export. One of the most common problems affecting boiler performance is the improper use and operation of boilers, inexperienced boiler operators, non-compliance with basic principles… So what can we do? to increase the efficiency of the boiler?
Measures to increase boiler efficiency you should know:
Adjustment of boiler steam pressure reduction:
Low steam pressure will result in low saturated steam temperature which in turn results in reduced heat loss on the distribution piping system, on valves and connections. This adjustment can reduce the amount of fuel burned by 1 to 2%. Besides, the pressure will also reduce the leakage of steam supply at the junction, valve, reduce the temperature of the water in the steam bag and reduce heat loss at the hot water contact surfaces. A decrease in the water temperature in the boiler will reduce the need for preheating the feed water. Furthermore, reducing the pressure will lower the flue gas temperature, which will significantly improve the boiler efficiency.
One thing to keep in mind is that reducing boiler pressure will make boiling in the pot more intense, causing water to be drawn into the steam system. Poor quality steam supply will damage and corrode valves, connections, piping, and overload the steam trap. An increased steam supply rate will increase frictional losses and lead to a decrease in pressure in the steam supply system, resulting in a shortage of steam supply.
Regularly monitor and adjust the fan and water pump properly:
Regularly monitoring and adjusting fan and water pump speeds is an important solution to achieving energy saving goals. This directly interferes with the fuel combustion process as well as the steam generation process, which greatly affects the efficiency of the boiler.
Check and blow down the boiler regularly
Regular boiler check and blowdown is important as this can help maintain the total dissolved solids within acceptable levels. If the amount of dissolved solids is too high, it will quickly lead to the formation of scales inside the boiler (boiler). Note that the boiler blowdown process (boiler) needs to be well controlled otherwise it will cause great waste. For example, with a blowdown of about 10% in the furnace with a pressure of 15kg/cm2, it will reduce the useful energy by up to 3%.
Common types of furnace blowdown:
– Intermittent boiler (boiler) blowdown system, this type of discharge can be operated manually or automatically controlled according to the repetition time.
– Boiler (boiler) blowdown system continuously.
The blowdown of this type of boiler (boiler) depends on the type of system, this work will be calculated to adjust the discharge time according to actual boiler (boiler) operating conditions.
Strict control of boiler load
The maximum boiler efficiency is achieved at about 70% of the maximum load and not at 100% full load. If the boiler load is even lower, the efficiency also tends to decrease. Therefore, to achieve high efficiency, it is recommended to regularly operate the boiler at a suitable high load mode, instead of operating at a low load mode.
It is necessary to consider and ensure the proper use of the boiler
