A dryback boiler has a rear wall that is lined with refractory, a wetback boiler has a rear wall that is jacketed by water. Because of this fact, wetback boilers typically boast higher efficiency than dryback boilers as the heat from combustion goes directly into heating water instead of refractory. Wetback boilers are also more forgiving with load changes as the reversal chamber of the boiler is totally submerged in water creating an even heat transfer on the intermediate tube sheet to furnace joint.
The service life of your industrial boiler is 15 years. Of course, there are a number of factors that may force you to replace your boiler before it reaches the 15-year mark. If there are obvious signs of wear and tear, you may not want to push the boiler much longer.
One of the most important accessories you can have for your steam boiler is a water softener, which serves several purposes and plays a crucial role in helping your boiler avoid malfunctions and run more efficiently. Let's go back to the basics and walk through how water softeners are used in steam boilers.
One of the most difficult questions of purchasing new boilers is deciding how many boilers will be necessary. The best way is to consult with an expert who can guide you through the process. However, there are two factors to consider before you speak to an expert.
Purchasing a new boiler is a big decision for any company or organization. It means investing thousands of dollars in a piece of equipment you’ll be using for many years to come. Needless to say, it’s not a venture you should take lightly. You need to know ahead of time exactly what you should be looking for in a new boiler.
Boilers are often distinguished by fuels that power them. The kind of fuel makes an essential difference in operating costs and environmental impact, so it’s important to learn about the various types of boiler fuel.
Coal, is a common boiler fuel. It dominates the global energy arena due to its abundance, affordability and wide distribution across the world. The most commonly used coal fuels include anthracite, bituminous coal, sub-bituminous coal, lignite and peat.
Any unusual noises should always be treated seriously.
One of the first things to check if a boiler is unusually noisy is the boiler's thermostat. If the thermostat is malfunctioning, water can become too hot and begin to boil, which could cause loud noises. If the thermostat is broken it may need to be replaced to prevent the water from heating up so much.
Another reason for a noisy boiler could be mineral deposits. As the water heats up inside the boiler, minerals may sink to the bottom of the tank and affect the heat exchange. This may create hot spots within the boiler in which water is overheated, leading to loud noises.
Low water pressure is also a concern that can result in loud noises. If water pressure is low, the boiler is tend to be overheat.
Today's businesses, regardless of industry, can always do more to improve their sustainability and limit the negative impact their actions have on the environment. There are a number of ways to do this, but one of the best is to use a boiler that's designed to limit the emissions of NOx — one of the most harmful greenhouse gases humans emit into the atmosphere. Aside from being good for the environment, a low NOx boiler can also be good for business.
