R.F. MacDonald Co. Refractory Dept. has instructed boilermakers how to repair boiler doors both in the shop and in the field for over 10 years. Knowing how to properly rebuild a boiler door is a boilermaker growth requirement at RFM. Our in-house Refractory Dept. provides training for boilermakers during level three of a five-level growth...
Cleaver-Brooks releases hydronic boiler animations, highlighting ClearFire boilers, skids and Alufer firetube technology. Product animations include: • Hydronic Skid Systems, which have variable flow primary design for maximum operating efficiency and lower total cost of ownership. • ClearFire Condensing Boilers, which have high mass, firetube design for variable flow primary systems, include Alufer technology for...
In condensing boilers, there is a direct correlation between increasing condensation of the flue gas and boiler efficiency gains. Boilers are closed pressure vessels that are used to heat fluids -- either water or steam. They range in size, fluid to be heated, temperature of fluid and design configurations. This paper is the first in...
The key to 99% efficiency is having incoming feedwater below 140° F and modulating the boiler — or having sufficient redundancy to achieve the “sweet spot.” Getting the most for your energy dollar It’s a clever idea. Condensing hydronic boilers can operate at efficiencies in the mid‐90s and above. The key to these fantastic efficiencies...
Today, hydronic boilers are producing greater efficiencies than previously thought possible — all due to the advancements of condensing technology. It is the science behind condensing that many people do not take the time to understand, which can lead to misunderstandings and the perpetuation of myths. One of the largest areas of confusion concerns high...
