People assume that owning a biomass boiler is no different from owning its less environmentally friendly cousins, the oil and gas boilers. Nothing could be further from the truth, and it is this very misconception which leads to abuse and neglect of the maintenance that a biomass boiler needs, if it is to retain its environmental and economic saving potential. This is especially true given the tendency of many installers to skimp on providing the proper support services and education to their customers.
Establishing a boiler water treatment plan will provide you with real-time feedback of your boiler system so you can get ahead of any issues that might occur as a result of poor water quality. We broke down the boiler water treatment process into three simple steps that you can incorporate into your preventative maintenance practices.
Water quality is of the utmost importance in proper and safe boiler operations. An improperly treated feedwater system can result in the scaling of the boiler internals, safety equipment and auxiliary piping.
The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels.
The construction and working principle of the boiler economizer is simple. At the bottom part, it has a horizontal inlet pipe through which we feed water with normal temperature to the economizer. There is another horizontal pipe fitted at the top of the economizer.
A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.
The integration of a biomass system is relatively simple. In most cases the systems are retro fitted and replace a fossil fuel boiler. The biomass boiler replaces the existing fossil fuel boiler, but the downstream heating system will remain the same, so there is no need to replace the radiators or whatever emitters are in place.
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
