Saving Boiler Fuel - Veolia Water

2015-11-3 · Saving Boiler Fuel By James McDonald, PE, CWT Originally Published: CSTR September 2005 O n average, approximately 75% of the operational costs for a boiler is fuel cost, as shown in Figure 1. Wat er management, sewer, and water respectively rank a far distant 5 th, 6 , and 7 th on this list, totaling a mere 4.25% of operating costs.

Stack Temperature and Burning Efficiency | …

2012-1-18 · With a thicker bed of coals my stack temperature goes down, quite a bit. Good gassification, better efficiency. Different types of wood effect that coal bed and therefor the stack temperature. How much the damper is open also has effects. Lots to learn. I also need a good stack temperature thermometer that measures on the inside of the pipe.

Low Temperature Corrosion in Boiler and Its Prevention

My hot water boiler keeps increasing pressure when it …

My hotwater boiler keeps increasing pressure when it runs. Normal pressure is 12psi but it has risen to as high as 40psi though the max pressure is indicated as 30psi on the gauge. I rcently replaced the flow control value which I set to the normal 12psi prior to use of the heater. The house is dual zoned and the problem occurs in bith zones.

Increasing stack temperature — Heating Help: The Wall

Increasing stack temperature. zeke Member Posts: Could anybody tell me the possible causes? Also I have never seen a tech test for CO. Am I missing something? I have seen some "techs" clean a boiler and "forget' to put the baffles back in the unit. or are they have slowly rotted out to the point where they are almost non-existant.

Best Practices for Condensing Boilers

2018-10-31 · A standard hot water supply temperature for a con-densing boiler should start at a minimum of 140°F (60°C) with the ability to go lower, provided enough heating capacity is available at a reasonable cost from the heating coils and terminal units. Although a lower water temperature may be possible…
