There’s no way to deny that the world of business is becoming increasingly competitive every day. Businesses need to reduce their operation cost to cope with the changing circumstances. One of the best ways for businesses to reduce operational cost is by installing energy-efficient equipment and gadgets, suggests Dan – a qualified plumber associated with Emergency Plumber Camden.
Cost-cutting approach with energy-efficient equipment is easily scalable. Once you start it, the effect will automatically show up in the form of lower utility bills in the subsequent months.
One of the best ways to cut down the operational cost is by investing in boiler maintenance, opine professionals providing boiler repair service in Camden. Proper maintenance of a boiler also increases its efficiency as well as expands its life.
How can boiler efficiency be increased?
The maximum heat loss in a boiler occurs at the stack or boiler water. Technically, you’ve to create conditions that generate the least amount of the exhaust gas at the minimal possible temperature to achieve boiler efficiency. In a boiler system, this exhaust gas or flue gas is the one which is expelled.
Now let’s put the mechanical thing aside and imagine:
The boiler sucks in cool air .from the surroundings heat it up and throws it out the stack. Ideally, the gas stack temperature has to be low or else the flue gas will take away more energy with it. On the other hand, the boiler system is designed such that it takes in cold water, transforms it to steam and uses up the heat in the process.
Once this basic mechanism is clear, it will be easier to follow the tips for boiler efficiency.
Tips for increasing boiler efficiency
- Take measures to minimise the temperature in the stack: Manually lower the operating pressure if you’ve steam boilers and if you have a hydronic boiler, lower the operating temperature – when the gadget is idle, like on fall days, mild spring or night time.
- Consider installing an economizer: An economiser uses the hot flue gas, which is otherwise wasted, to heat up the feed-water on its way to feed the boiler. When a steam boiler does not have an economiser or if the economiser is not working properly, you should resolve the issue on a priority basis. Moreover, economisers save fuel. There are many varieties and brands of this supporting component available in the market. Ask your regular plumber to suggest one that suits you the best.
- Tune the burner at regular intervals: Certain quantity of oxygen is needed for proper combustion of the fuel inside a boiler. When there is less oxygen than what is required, the fuel is partially oxidized creating carbon monoxide, soot and smoke – which all are harmful both for your health and environment. As the fuel could not burn completely, less heat is produced and this factor takes a toll on boiler efficiency.
- Installation of Variable Frequency Drive (VFD): When a valve or damper controls the circulation pump or fan in your boiler system, a lot of electricity is being consumed while running it on partial load. A VFD – on the other hand – allows the boiler to control the flow with the pump speed or fan. As a result, the electricity consumption of the system comes down drastically. Emergency Plumber Camden has an efficient and experienced plumber for an emergency boiler repair in Camden. These plumbers suggest installing a VFD to your boiler system to improve efficiency.
- Valve insulation is crucial: It is common in plants that people remove the valve insulation in the boiler room while performing maintenance service and never bother to put it back. This causes immense heat loss, making the boiler room excessively hot. Removable blankets are available in the market to insulate boiler valves. These specially designed blankets reduce risks of burn, keep your boiler room somewhat comfortable and allow easy access to valves for maintenance.
- Fireside cleaning: Soot builds up over time on the fireside of the boiler tubes. This soot plays the role of an insulator, affecting the heat transfer rate and increasing fuel consumption. Lower heat transfer rate in the system prevents hot gases from transferring heat to the water. As a result, the stack temperature rises. To avoid this hassle you need to clean and maintain the boiler tube at routine intervals to prevent soot buildup.
- Keep the waterside clean: It is important to keep the waterside of a boiler clean and leak-free. Inspect the boiler side at short intervals and clean any mud legs or mud drums that may build up. Your effort will ensure a high rate of heat transfer from the metal body to the water. If the hardness of the water is too high or not properly treated, a scale will form on its own around the surface of heat transfer reducing boiler efficiency. To cut a long story short, this overall development will cause overheating of the boiler, making it prone to leaks and defects.
- Recover the heat generated from boiler blowdown: Recovering the heat generated from boiler blowdown is vital to boost the efficiency of the system. The blowdown valve facilitates removing the boiler water, which contains many impurities dissolved in it. When the valve removes hot water, it practically wastes energy. You can install a blowdown heat exchanger, a flash tank or a combination of both to recover a significant part of that wasted energy. Energy efficiency automatically gets improved when you recover the heat.
There are more tips on improving boiler efficiency, but boiler repair experts in Camden suggest if you follow the basic tips discussed above, much of your goal will be achieved. Master these tips before moving on to more advanced options.
