High flow rates. Separate stainless steel flat plate heat exchanger for DHW creates one of the highest flow rate for any combi‑boiler in the industry. (NFC up to 5.4 GPM @ 67º temperature rise; NCB-E up to 4.5 GPM @ 77º temperature rise)
Another tool used in boiler calculation is the pressure-enthalpy diagram for steam/water (figure 5). With the p-h diagram it is easy to visualize the partial shares of the total heat load on different heat exchanger surfaces in the boiler: drawing the steam heating process in the boiler onto the p-h diagram will give a horizontal line (if we

The boiler room will require a minimum of two fresh air opening of 22.66 sq. ft. (45.32 sq. ft ) 2) net free open area. NOTE: For all applications, the above is a general minimum requirement for fresh air supply. Always consult local codes which may supersede the above recommendations.
Causes, and prevention of scaling in boilers, type of scaling. Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.
8/16/2017 · This rating assumes the boiler is in an unheated space. 2) Net IBR Output: This is a further arbitrary deduction of 15 per cent from the IBR Gross Output that takes into account the losses from the distribution piping and the necessary Btus it takes to bring the system up to operating temperature, or in other words pick up allowances.
1. The BASE flow rate has been established at 20 gpm 2. We will on next slide need to add for bypass flow, which can add 10 to 20 percent to the BASE flow rate 3. Blowdown flow is to be approximately 10 percent of flow at pump’s Best Efficiency Point 4. So the total boiler blowdown flow required is approximately 3 gpm 45
A properly sized feedwater system will have a tank adequately sized to feed your boiler and pumps selected to deliver that water at the correct rate and pressure. CALCULATE THE STORAGE TANK NEEDED. In most cases ten minutes of water should be readily available for your boiler. One boiler horsepower = 34.5 lbs/hr of steam (or water) from and at ...
If boiler and boiler feed unit are on the same floor, enter a value of "0" for feet of head. If boiler is located on a floor above the boiler feed unit, enter vertical height (in feet) from the pump discharge of the boiler feed pump up to the inlet piping on the boiler. Assumes pressure drop through modulating valve of 10 psig or less.

Regular maintenance and cleaning, often called a tune-up, keep your boiler running efficiently and inspects for any potential issues. Most professionals charge a flat rate for regular maintenance calls and often offer annual service plans.
Specifically, the net steaming rate equals the gross steaming rate minus the steaming rate to the feedwater receiver. Except for some very unusual applications, the net steaming rate is less than the gross or "from and at 212°F" steaming rate.

4. Calculate the Net Flow Rate of each Boiler Feed Pump. The Third Step is to calculate the flow required for each boiler feed pump. Net Pump Flow Rate = Boiler Evaporation Rate + Catch Up Capacity. 1. Boiler Evaporation Rate a. Boiler Capacity = System Load + Blowdown + Steam to DA b. Boiler Evaporation Rate = Boiler Capacity(pph)/500 2.
pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.
