The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Nov 07, 2019 · When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.
Highest boiler water temperature is 95°C (control thermostat). Minimum return water temperature is 20°C at a flow rate related at a ∆t of 20°C (flow/return temperature). 4.1.2 Water pressure Boiler sections pressure test at 12 bar. Maximum pressure test for the boiler block is 6 bar. Minimum working pressure boiler is 0.8 bar.
Jul 03, 2017 · So e.g. if your pressure vessel is fed by a pump which has say a normal operating pressure of 5 bar, but on no flow the inlet pressure to the pump increases and then the no flow differential pressure increases and so the max pressure from the pump is 10 bar. So if you had set the design pressure of the vessel at say 7 bar, then you now need

What Should The Boiler Pressure Be When The Heating Is On?
May 26, 2021 · A combi boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it's likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal. A consistent 3 – 4 bar, however, is something to raise with
Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Energy Star rated 85% efficiency.
Click to enlarge and you can see the actual pressure settings on the steam boiler control shown at left. 0.2 psi = 0.014 Bar or about 1378 Pascal of pressure - typical low-end of residential steam boiler pressure settings. 0.5 psi = 0.034 Bar or about 3447 Pascal of pressure - typical high-end of residential steam boiler pressure settings.
Aug 31, 2010 · If you have just run water from a group the pressure will climb above brew pressure as the cold water that has just entered the boiler increases in temperature, expands and therefore increases boiler pressure. The thermal expansion valve opens to relieve the expansion pressure and it is usually set at around 12 bar.
Steam Tables. Steam and temperature posess a reliable realtionship whereby if the pressure of the steam is know its temperature can be predicted (and vice versa). Below is a graph and table of this relationship. Gauge Pressure (BAR) Temperature °C. Gauge Pressure (BAR) Temperature °C. Gauge Pressure (BAR)
a) boiler b) high temperature furnace c) compressor d) gas turbine 12. The device used to upgrade a lower pressure steam to a higher pressure steam is called a) heat pump b) thermo compressor c) heat pipe d) heat wheel 13.
