used hot water boilers ebayfire tube horizontal

Pressure used hot water boilers ebayfire tube horizontal is usually set at the top of the atmosphere through a port, the internal pressure and external pressure to maintain a balance, high safety factor, little explosion or other accident occurs suddenly, often used in residential or office buildings or provide domestic water and heating.

Recently, the Longhai carried out safety campaigns to the boiler, the campaigns start from the four directions, whether units in accordance with the boiler 'boiler safety practices "to use the correct boiler conducted a comprehensive inspection.

First, the unit register in a boiler boiler inspection. The use of units to crack down on unauthorized use of untested or failed the inspection of boilers.

Second, the units are equipped with a boiler if the security officer and fireman personnel. Focus on checking whether the use of units as required "special equipment operator assessment rules," the fireman with security personnel and staff to meet the requirements, and whether the person has made fireman fireman card.

Third, in the boiler unit will be the safety management system, emergency plans to check the system; and to convey the importance of this inspection in the boiler unit, raise awareness of security units.

Fourth, strengthen supervision of energy-efficient boilers, boiler and actively promote energy efficiency testing, at present, boiler energy efficiency testing has been completed a total of 112 units.

To date, the Longhai inspection operations were dispatched inspectors 209 passengers, checked boiler unit 136, check the boiler 168 units, eliminate safety hazards at 9, and urge the use of sealed units to enhance the energy efficiency of boilers 21 units.

And with the Commission by letter, and environmental protection departments to further promote the comprehensive upgrade of coal-fired boiler energy saving project, disable the coal-fired boiler 53 units, 34 units scrapped, replaced by raw material boiler fuel and natural gas fuel of a total of 40 units, is out of the city coal-fired boilers to make a positive response.

Effect of gas pressure changes in the gas kotelshchik gas boiler conditions during operation, the gas for combustion to the burner, when gas pressure changes, the change will lead to the gas entering the burner, this will affect the proportion of air and gas, whereby have some impact. The results caused by the gas pressure changes are the following possibilities: 1, hypoxia combustion: gas pressure suddenly increased, it is easy to burn the absence of oxygen occurs, resulting in incomplete combustion of gas, flue gas will be carbon monoxide, thermal efficiency of gas boilers have loss. 2, from the fire: if the gas pressure, the gas stream will cause the gas velocity greater than the burning rate, the flame away from the fire resulting from the flame hole edge called on to develop from the fire. This situation will result in flame or combustion instability, and even lead to security risks. General machinery comes with a high-pressure blast burner control, when the gas pressure exceeds a defined value the active flame protection. 3, the combustion peroxy: this occurs in the gas pressure is reduced, excess air appears, nitrogen and oxygen in the air reaction, resulting in excessive emission of nitrogen oxides. 4, tempering: If the gas pressure is very small, it will cause the gas flow velocity is less than the gas combustion speed, causing the flame tempering, influence the safe operation of the burner. General machinery blast burner comes with a low pressure control, when the gas pressure exceeds a defined value the active flame protection. When the gas pressure exceeds the operating range of the burner, the flame will be deformed, fireman gas boiler can operate normally whether this phenomenon was observed.

requirements for protection devices for oil-fired boilers and requirements for furnace operators

In the last article, we discussed the safety of the oil-fired boiler. On the basis of this, we talked about the safety requirements of the boiler room. In fact, in addition to its accident, there are also boiler protection requirements and boiler operators' requirements for the construction of a safe environment.
