The suspended and released magnetic oxide moves to and accumulates in low flow or high heat flux areas of the boiler. While caustic attack is sometimes referred to as caustic pitting, the attack physically appears as irregular gouging or thinning and should not be confused with the concentrated, localized pit penetration representative of oxygen or acid attack.

Understanding primary-secondary pumping

2014/6/23 · Primary-secondary pumping lets you use small, inline circulators - even on large commercial jobs - and that's a real plus. And in a multiple-boiler system, this simple method of piping gives you a way to lower boiler standby losses and save fuel. When piped properly, no water will flow through an "off" boiler when its secondary circulator stops

Boiler Combustion | CleanBoiler.org

Older boilers generally have higher levels of CO than new equipment because CO has only recently become a concern and older burners were not designed to achieve low CO levels. In today's equipment, high levels of carbon monoxide emissions primarily result from incomplete combustion due to poor burner design or firing conditions (for example, an improper air-to-fuel ratio) or possibly a leaky

Boiler – Fundamentals and Best Practices

Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

Economizer - an overview | ScienceDirect Topics

In shell boilers with a working pressure of between 7 and 17 bar the temperature of the mass of water in the boiler is typically in the range of 170–210 C. Allowing for, say a temperature difference of 30–50°C between the exhaust gases and the water temperature, the boiler exit gas temperature cannot be economically reduced beneath about 200–260°C, dependent on the operating pressure.

Sizing a Modulating Condensing Boiler - GreenBuildingAdvisor

2016/5/24 · For the past few decades, an increasingly popular space heating option is a system with a modulating condensing (mod-con) boiler. Because these boilers can potentially have a high efficiency (90-95% or higher), they are often promoted by state and utility subsidy programs. In a well-designed system, the boiler's efficiency can hit or even exceed its nameplate AFUE. But as installed, most
