Changes with the seasons or otherwise affect, the user demand for heat output of the boiler also vary, fast low-nitrogen side condensing gas boiler may employ a plurality of combined control mode of operation, according to the different needs of the user adjust the number of operating flexibility, can meet user needs, but also avoid unnecessary waste.
Gas boiler safety rules recently customers find us, consult safety procedures and precautions gas boiler, for you this question, our technical staff providing answers. Gas boiler safety procedures and precautions. ① When the gas boiler body found abnormal phenomenon, how to do security incidents shutdown control device failure should move off the emergency button to stop the boiler operation; ② boiler feed pump damage, mediation device failure, emergency disconnect button should move, stop boiler operation; ③ when faced with a problem of power fuels take off pressing the emergency button; ④ when the boiler or jeopardize the safety of the phenomenon should be taken to an emergency shutdown; 5. Start and stop by the boiler burner is issued by the controller to start and stop instruction according to pressure changes (this function is automatic) The operator should always observe the change in pressure can occur if the abnormal stop immediately, cease-fire. 6. You should always observe the water level, in particular to ensure that the boiler operation fill the tank full of water during operation. The operator shall periodically to the boiler blowdown, boiler water quality assurance. 7. Once the boiler during operation anomalies operators should be shut down immediately after treatment failure re-boot. 8. A burner for a three-phase power supply the operator should be determined before the first start motor forward, reverse, or can not normal ignition. (At this time, the fan stops burner ten seconds after the start, the alarm control box).
An important problem is the quality of the selection of gas-fired boilers have to consider, to solve this problem involves two steps:
Recently, the Tianjin Municipal Government issued the latest "2018 ~ 2019 autumn and winter tackling air pollution comprehensive management action plan" (the "Program"), "plan" put forward specific remediation requirements: the city's 65 steam tons / hour and above the basic realization of coal-fired boilers coal-fired power plant ultra-low emission standards, the development of energy-saving and ultra-low emissions rehabilitation programs for 65 steam tons / hour or more coal-fired boilers, the implementation started after the end of the heating season. Before the end of this year, within the city basically eliminated 35 tons of steam / h and coal-fired boilers of 25 iron and steel industrial enterprises discharge waste depths of governance, the basic completion of the iron and steel, building materials, thermal power, coking, casting and other key industries and coal-fired boiler fugitive emissions control.
"Plan" the implementation process to uphold the objectives warm winter and clean heating double standards, combined with the actual development of coal-fired boiler rehabilitation programs, to ensure completion before the end of the year 206,100 rural residents to use clean energy alternative to coal for combustion. Guidelines established after the first break, for the substitution of gas for coal to electricity instead of coal and other alternatives, in the case of gas supply, power supply is not implemented, the existing heating facilities will not be dismantled until the gas supply, power supply after the successful implementation be removed. And to develop high-pollution fuel combustion zone ban zoning adjustment programs, complete with electricity instead of coal, substitution of gas for coal in the region included the range of high-pollution fuel combustion zone ban. For failure to implement the heating area clean, good smokeless coal tender, production, supply, to ensure smokeless coal substitute the existing polluting large coal-fired boilers. Among them, before the heating period to complete large-scale centralized distribution, heating Doing the fragmented coal blending, before the end of December 2018, the actual realization of bulk coal dealers cleared.
Nov 17, 2008 · My hot water boiler keeps increasing pressure when it runs. The other reason for high pressure would be a bad feeder which you said you replaced. Now that you have drain the tank, see if the pressure stays below 20 PSI. I may have overlooked the obvious here and it's possible that your pressure gauge is way off.Get A Quote
Nov 17, 2008 · 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.Get A Quote
Possess a blue seal boiler operator's license for a period of at least one year and show experience on equipment that is over 1,000 boiler horsepower. Equipment must be high-pressure boiler equipment, which means the boilers must be over 15 psi for steam and over 160 PSI for hot water.Get A Quote
The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.Get A Quote

The boiling point of water depends on pressure. Online Water Boiling Point Calculator. The calculator below can be used to calculate the water boiling point at given absolute pressures. The output temperature is given as °C, °F, K and °R. Note! Pressure must be within the ranges 1-220 bara, 14.7-3200 psia, 760-165 000 mm Hg or 30-6500 in Hg.Get A Quote
Drain water out of the boiler's drain valve. This valve is located at the bottom of the boiler. The valve looks like a water spigot you would find on the outside of your house. Turn the handle counterclockwise to open the valve. Drain water until the pressure gauge reads 10 psi (pounds per square inch).Get A Quote
Dec 31, 2013 · The standard setting is 12 lbs cold. 1 PSI will raise water in a column 2.31 feet. The pressure should be set to what is required in total height of system. For example, if a boiler is in the basement, and its a 2 story house with baseboard radiation on the second floor, it could be 8' + 9' + 1' = 18' (boiler to upper baseboard). 1 PSI / 2.31 = 0.4329Get A Quote
The US Navy operated 1200 psi boilers for many years. High pressure steam generators in Nuclear plants are usually limited to 600 psi due to the lack of superheating.Get A Quote

While not every boiler has the same pressure requirements, most central heating systems perform within the range of 1 to 2 bar, which is between 14 and 29 pounds per square inch (psi). The exact pressure of your combination and system boiler can be measured on the boiler pressure gauge, which is generally visible on the front of the control panel.Get A Quote
This pressure is measured in terms of pounds per square inch or psi, and gauge pressure is expressed as psig. The National Fire Prevention Association and federal standards define a Type II steam boiler as one that produces high-pressure steam between 16 and 150 psig. A Type III steam boiler produces steam between 151 and 350 psig.Get A Quote
