This can occur in pressurized systems, such as boilers, chemical feed pumps, elevated tanks, recirculating systems, or in a pump used to increase water pressure within the building's plumbing system to reach a higher floor. Back-Siphonage: This occurs when there is a negative pressure in the water distribution system.Get Price
Negative pressure can cause backdrafting and prolonged spillage from fireplaces, gas-fired water heaters, furnaces, boilers, or any other device that uses house air for combustion. It can also cause flame roll-out from the bottom of residential water heaters and increased carbon monoxide production in both water heaters and furnaces. Moisture/MoldGet Price

Feb 01, 2010 · In one building, the control panel was in the penthouse mechanical room, which was open to the outside via boiler outside-air-intake louvers. While that location was good for minimizing wind effects and protecting the sensor from rain, readings likely were not representative of true outside-air static pressure because the panel was in a room containing …Get Price
Back-siphonage is caused by a negative pressure ( i.e., a vacuum or partial vacuum) in a public water system. The effect is similar to drinking water A pressure vacuum breaker is an approved backflow prevention device designed to Backflow of boiler corrosion control chemicals onto an office building's water supply.Get Price

WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. The boiler is equipped with an advanced burner, an economizer and a condenser, which can improve the thermal efficiency to more than 98% and reduce the NOx emission to less than 30mg/Nm³.Get Price
The major change when replacing standard boilers with condensing boilers is dealing with the condensate, the flues now must be sealed as the boiler flue gasses will be wet, cool and under a positive pressure while on older conventional boilers the flue gases will be hot and under a negative pressure. As the condensing boiler flue gas discharge Get Price
11 rows · Gas(oil) Fired Water Tube Hot Water Boiler. The boiler is a double-drum longitudinal "D" type structure. The water, steam or steam-water mixture flows in the tubes. The flame burns and the flue gas flows outside the tubes, to ensure the good water circulation system, thus ensuring the long-term stable operation of the boiler. Get Price
Gas(oil) Fired Water Tube Steam Boiler. 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 flow rate and excellent water circulation system.Get Price
