Acme boilers installation The ultra-efficient, electric boiler design eliminates many environmental issues associated with fuel burning boilers, such as fuel fumes, fly ash, and large obtrusive exhaust stacks
Output control
High voltage electric boilers also offer superior control of energy output. The control system automatically monitors factors such as water level, steam pressure, conductivity, and electrical imbalances so energy input and adjustment is precise, and virtually immediate. As an example, advanced high voltage electrode steam boilers can control the capacity
progressively from 0%-100% and have a 100% turndown ratio (the ratio between a boiler’s maximum and minimum output). Most gas boilers have a ratio of 10:1 or 5:1, which means the units require a much higher minimum output level to function and take a significant time to reach full capacity.
High voltage immersion steam boilers can control the capacity progressively from 10%-100%. Increased safety
High voltage electric boilers can be safer to use than traditional, combustion-fueled boilers, which can emit harmful vapors, leak gas, and even cause explosions and fires. In gas-fired boilers, explosions can result in the ignition and instantaneous combustion of highly flammable gas, vapor, or dust that has accumulated in a boiler. The force of the explosion is often much greater than the boiler combustion chamber can withstand. Minor explosions, known as flarebacks or blowbacks, can also suddenly blow flames many feet from firing doors and observation ports, seriously burning anyone in the path of a flame. Natural gas-fired boiler emissions also pose potential hazards in the form of emissions. In addition, fossil fuel burning boilers can face potentially dangerous operational issues stemming from excessive heat accumulation. Modern electric boilers eliminate many of these risks, so can dramatically improve both operator and environmental safety. With the jet type electrode boilers, there are no combustion hazards because there are no flames, fumes, fuel lines or storage tanks, which minimises the risk of explosions and fires. In case of an electrical short, the breaker that protects the high voltage circuit trips in a matter of milliseconds, protecting the boiler and the electrical network. There is no chance of electrical mishap or fire from the boiler. Since the design does not rely on combustion, it does not create emissions that would endanger the operator or environment. In addition, the design eliminates common environmental problems associated with fossil fuel burning boilers such as fuel fumes, fly ash, and large obtrusive exhaust stacks. Although consulting engineers are experts in their designated fields of expertise, keeping up to date with the latest developments in advanced electric boiler technology can provide significant advantages in providing hot water and steam for a variety of industrial purposes. Understanding how to select, specify, and install electric boilers for the specific situation will conserve substantial energy, space, and resources compared to fuel-fired options. In addition, it will not only facilitate project success but also a safer environment that helps combat global warming.
