No matter what type or size of boiler you are looking to purchase, there is always one question you must always answer when selecting a steam boiler: What is the basis for design? Fulton Company recently published a list of 10 features you wish every boiler had. It is important to review this list and be sure to know which attributes are most important to you and your specific application. In addition, when selecting the right boiler provider, remember that any qualified boiler company should be able to provide you with accurate boiler specifications, performance data, and drawings, all of which will make the decision process easier and will help you along the boiler decision process.
*** With emission requirements changing everyday, it is also important to make sure that you are proactive when selecting equipment that will comply with future air regulations. Nationwide Boiler has the most experience in selecting boiler equipment that will meet current and future NOx requirements and we developed the CataStak SCR system as a solution for ULN compliance.

1. High Pressure Vessel Mass
The mass of the boiler will be a good indication of the amount of metal used to manufacture the pressure vessel. Mass is related to thickness and thickness is related to durability. Inherently, low mass boilers will not last as long as high mass boilers.
2. High Water Volume
Water under pressure will store steam. Higher water volume means higher stored steam. Applications where you have rapid swing loads will require a high water volume boiler design.
3. High Efficiency
We all would like to have the most efficient boiler. Efficiency, however, must be defined and compared on equal terms. Ensure boiler pressure, feed water temperature, firing rate, fuel BTU value and stack CO2 levels are all defined on the same playing field.
4. Quick Startup Times
Simply put, you want steam in a reasonable time frame. Boilers that can make steam quickly likely will have low water and low mass, which may be non-desirable features. One must also realize a quick startup will facilitate a quicker cool down. The boilers on the market today typically require 5 to 20 minutes startup time or more, depending on the size of the boiler
5. Low Footprint
Boiler room real estate is quite valuable these days and the less room a boiler occupies, the better. Be sure you take into consideration the amount of room required to perform maintenance on the boiler as part of the overall footprint.
6. Low Heat Flux and High Heating Surface Area
Heat transfer is represented by the equation
Q =m x Cp x ?T
where m is the heating surface area.
Most heating surface area listings are for the fire-side surface area, with higher fire-side surface area values indicating higher the heat transfer efficiency. However, one also must consider the wetted heating surface area. The wetted heating surface area determines heat flux. Consequently, low wetted heating surface area can have very high heat flux, which can create higher metal temperature and increase scaling potential.
Boilers with high fire-side and high wetted heating surface areas will be the most efficient and have low heat flux.
7. Ease of Clean Out
This is a measure of effectiveness of blow down and ability to keep the pressure vessel clean.
8. Effective Turndown
This feature has a lot to do with the burner performance. Effective turndown is a measure of how low the fuel input and air can be adjusted to maintain good combustion efficiency. Some burners will turn down the fuel but leave high excess air on low fire. This will create high turndown but poor overall combustion efficiency. Look at the highest turndown level while still maintaining good combustion efficiency.
9. Ease of Maintenance
Hardly ever will a specifying engineer think about maintenance when selecting a boiler. They should. Blow down valves, stack location, feed water inlet, control panel location, tube removal, burner removal and gas piping maintenance should all be considered as criteria of boiler selection.
10. Large Steam Disengagement Area
Like heating surface area, the more steam disengagement area, the better. Higher steam disengagement area produces higher steam quality, especially for low pressure steam applications. Consequently, horizontal boilers generally will produce higher steam quality than a vertical boiler of the same output.

If you run a brewery, you&#;re well aware of how many ways a steam boiler are used in the brewing process. You need hot water for wort boiling, and steam for sanitization, sterilization, and pasteurization during the kegging, bottling, or canning process. If you distill other liquors, your steam boiler is also needed for the distillation process.
But if you&#;re looking for a boiler, you may not know exactly what you should look for. Should you choose a conventional fire tube or a compact water tube steam boiler? The following 6 tips should go a long way in helping you choose the right boiler for your busy brewery or distillery.
Due to long warmup times, most 24-hour brewery operations choose to leave their large boilers running all the time, but this is inefficient for smaller craft breweries and can result in higher fuel bills. A Miura modular boiler installation is a good fit for craft breweries because these smaller operations only run maybe one or two brew shifts per day at the most. With a modular boiler system from Miura, if you don&#;t need the boiler running outside of these brew shifts, you can turn it off. You don&#;t have to keep it hot and on standby like a conventional fire tube boiler.
Space is often a premium for smaller breweries, which is why they often have to get creative when designing their brewery boiler room. That&#;s why you should opt for a boiler that has a small footprint. Doing so means you will have room if you need to add another boiler down the road as your business grows. With their compact, modular design, Miura boilers are a great choice if you&#;re looking to maximize physical space. And when it comes to steam production, you get the same output compared to larger boilers that take up much more space.

Working with a company that provides excellent support is crucial to keeping your boiler running like new. Miura works with local dealers with the skills to provide expert installation and ongoing support. If you opt for Miura&#;s Online Maintenance (MOM) support system, Miura will monitor your boiler&#;s operating condition. The MOM system will also connect to expert engineers at Miura should any problems arise.
Miura also provides regular maintenance, but that doesn&#;t mean you&#;ll lose a full day of work when it&#;s time for service. Miura boilers need just 3 hours for a routine inspection. While one boiler is being inspected, your other Miura boilers can remain operating. Emergency service is also available when necessary. Keeping your boiler in top condition is critical to the operation of your brewery, and Miura provides everything you need to keep your boiler up and running.
If you&#;re in the market for an eco-friendly boiler that reduces emissions, look no further. When you choose a Miura boiler, you get a boiler that has a low nitrogen oxide and carbon monoxide output. If you run a brewery in a state with strict air quality regulations, like California, you need a Miura boiler to meet their strict rules.
Like any other company, a brewery is in business to make a profit. When you&#;re a small craft brewery, a conventional boiler can drain your profits quickly due to the need for constant uptime. If you want to improve your bottom line, Miura boilers are highly efficient, thanks to their &#;once-through&#; fin-tube design that conserves gas, space, and water but has BHP output similar to larger units. With long-term use, these cost-efficient boilers can save you thousands of dollars compared to conventional boilers.
You&#;re obviously not the only craft brewery looking for a cost-efficient solution to your need for steam&#;so it can help to look at what your competitors are choosing. Many craft beer breweries choose Miura boilers for on-demand steam, as well as a number of distilleries. We&#;ve compiled a few examples below for you to check out:
