1. The fuel volume is 1 / 30 ~ 40 of the raw material volume after molding;
2. The specific gravity is 10-15 times of the raw material, and the moisture content is between 12% and 18% (the moisture content of coal is below 10-15);
3. The net calorific value can reach 3500-4500 kcal (the net calorific value of class II bituminous coal is 3700-4700 kcal / kg);
4. The ash content is less than 10% (the ash content of coal is more than 20%);
5. Volatile matter ≥ 65.62% (volatile matter of class II bituminous coal≥20%).
6. Biomass fuel belongs to renewable clean energy, which is the same as wind energy and solar energy. The biomass fuel is rich in resources, it can ensure the sustainable use of energy.
7. The sulfur content and nitrogen content of biomass fuel are low, the amount of SOx and NOx generated in the combustion process is low.
Condensing boilers can achieve up to 98% thermal efficiency, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies over 90% when the return water temperature is at 110 ºF or less; the lower the return water temperature, the higher the efficiency gain.
The primary purpose of the boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process, laundry, kitchen, etc. The nature of the facility's operation will dictate whether a steam or hot water boiler should be used. Hot water is commonly used in heating applications, with the boiler supplying water to the system at 120°F to 220°F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig (hydrostatic). Under these conditions, there is a wide range of hot water boiler products available. If system requirements are for hot water of more than 250°F, a high-temperature water boiler should be considered.
Retrofitting a piece of equipment or an existing industrial heating system can be very challenging, but it can be especially frustrating if you haven't planned well ahead of time. You'll want to be sure that you've done your homework to ensure that retrofitting the piece of equipment you have in the way you have in mind is actually possible.
If it is possible, you'll want to work with the appropriate engineers to figure out exactly what it will entail, how much it will cost, what impact it will have on operations, etc.
ASME code – also known by its longer name: ASME Boiler & Pressure Vessel Code – regulates the design, development, and manufacturing of boilers used in a variety of industries and applications.
This code was developed by the American Society of Mechanical Engineers, an organization that has been around for well over 100 years and is focused on establishing safety codes and standards for mechanical equipment.
Within the industrial heating industry, ASME code is the established standard that many pieces of equipment are built to.
Heating systems that adhere to the specifications set forth by ASME code have been constructed according to guidelines intended to promote safety and quality. As such, heating equipment that is ASME code compliant has been thoroughly inspected to assure that it meets high safety and quality standards.
Unfortunately, there's no one-size-fits-all answer to this question. The overall cost of purchasing new equipment and implementing a new system will depend largely on a number of factors that vary for each different customer.
While we can't tell you exactly what you should plan to spend, we can give you some information on what will impact the price of the equipment you purchase.
Read on to find out what factors will influence how much you will spend on thermal fluid heating equipment for your plant.
All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system - which is why regulating the emissions of industrial boilers is taken very seriously.
In a water tube steam boiler, unlike a fire tube, water circulates inside the tubes. The heat that is generated and the combustion gases that surround the tubes heat the water that circulates inside them. Many water-tube boilers operate according to the principle of natural water circulation.
The capacity of this type of boiler can be enhanced by increasing the number of tubes in the boiler.
