attractive oil gas fired steam boiler

Boiler water treatment analysis of safety issues: the problem of boiler water treatment is an important part of the process of the safe use of boilers in general we all know that the market is now using more coal-fired attractive oil fired steam boiler, steam boiler fuel ratio or gas accounts for a large steam boiler most, especially in the current market share of imports of fuel gas-fired boiler in the market constantly rising, mainly due to fuel gas-fired boiler of compact, small size, high water quality requirements, at the same time, due to the oil and gas combustion temperature itself relatively high, therefore, be able to do is very important for boiler water treatment, boiler water treatment, if done well it will cause boiler fouling, corrosion, which not only wastes fuel and it can lead to blocked pipes, burst pipes and other accidents, and more there will also be scrapped boiler caused severe economic losses ***. Therefore, fuel oil and natural gas boilers must strictly check boiler water treatment problem seriously.

1, the boiler ready distal spacing of not less than 2/3 of the length of the furnace, and not less than 2 m; vertical boiler can be shortened; bulk boiler is not less than 4 m, and does not affect the operation and maintenance furnace.

2, the boiler side and rear channel spacing of not less than 0.8 m, and should meet the operational and maintenance (such as replacement tube bundle cleaning, stirring the fire, etc.) requirements.

3, the top horizontal boiler headroom not less than 2 m; vertical boiler top clearance height to facilitate the operation and maintenance; headroom boiler room the other channels, should not be less than 2 meters, when the passage of time and no need to operate its headroom height of 0.7 meters.

4, the boiler room is provided for two or more boilers, the boiler the distance between adjacent cylinder not less than 1.5 times the diameter of the boiler.

5, the boiler room is generally preferred fireman operation chamber provided, on the total rated greater than or equal evaporation 4t / h steam boiler (heating or hot water boiler is equal to or greater than 2.8MW) must be provided stoker operating room. Electric boiler tank may be provided in front of the boiler, and to ensure the art to fireman facing boiler water gauge, pressure gauge and other instruments during operation.

6, total rated evaporation is greater than 2t / h of oil, gas boiler room should be set foam fire extinguisher or water spraying systems, Outdoor proper outdoor fire hydrant, other boiler room should also have fire-fighting equipment.

7, the fuel in the boiler room daily oil tank, the oil pump is generally not located in the boiler room, between daily oil tank, the oil pump between the application of the fire resistance of greater than 2.00h wall, the fire resistance of greater than 1.50h floor spaced from the other parts. Daily fuel tank between the boiler room and the door between the oil pump should be able to self-closing fire doors Class A, and let the oil block measures. Household upper tank return pipe to be provided, should be greater than the oil return pipe back to the oil pump.

8, an oil tank and all piping must have a reliable electrostatic grounding, the grounding resistance should not exceed 30 ohms.

To implement the "Blue Sky Hohhot to win the Battle of three-year action plan," Hohhot ecological Environment Agency and vigorously promote the city's coal-fired boilers mentioned standard transformation and treatment, formulated the "65 steam tons / hour or more coal-fired boiler and governance to promote the program." clearly this year will focus on the 65 steam tons / hour or more coal-fired boilers and in particular the implementation of ultra low emission limit values ​​renovation work to further reduce emissions from coal-fired boiler pollution, improve the city's quality of atmospheric environment.

Program clearly states that the city has 58 coal-fired boilers will be completed before the end of the transformation, in which five large-scale district heating enterprises 65 steam tons / hour and over the implementation of ultra-low emission coal-fired boilers transformation,

16 65 steam tons / hour or more coal-fired hot water boiler to complete the transformation of governance. To ensure the smooth implementation of the mentioned standard treatment project, municipal environment bureau called on all localities in strict accordance with the "grid" management approach, down to every level will be the task of transformation, to the people, the letter coal-fired boiler to complete the task, each Related enterprises should play the main role, strict compliance with environmental laws and regulations and energy-saving standards, to complete the task on time.

To step up supervision and municipal environment bureau set up a special steering committee to implement the "Fortnight scheduling system", the city's coal-fired boilers governance supervision, the work of the task is not implemented, governance behind schedule, promote ineffective areas and enterprises to implement early warning and interviews, due to the unfinished task of accountability.

Types of High Pressure Boilers

A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas, also have high pressure steam boiler and high pressure hot water boiler. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces that burn 6 tons of coal a minute. Boilers operate at positive pressure, and all parts must be strong enough to withstand the pressure of the steam they generate. Most high-pressure boilers are used for commercial or industrial purposes.
