Water Handbook - Preboiler & Industrial Boiler Corrosion

The ASME Consensus for Industrial (see Chapter 13) specifies levels of contaminants for corrosion and deposition control in systems The consensus is that feedwater oxygen iron and copper content should be very low (eg less than 7 ppb oxygen 20 ppb iron and 15 ppb copper for a 900 psig ) and that pH should be

What is Boiler Draught? Types Classification Advantages

· The pressure available for producing natural draught by the chimney is hardly 10 to 20 mm of water under the normal atmospheric and flue temperatures The available draught reduces with increases in outside air temperature and for generating enough draught the have to be discharged at relatively high temperatures

How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3 pressure 8-10Kpa and theoretically the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 094) =297m3/h here we take 4 tons of natural gas boilers for example then the boiler gas
