what is the abc in boiler

6, the exhaust gas temperature should not exceed 300 ℃, shutdown or should be checked;

7, when gas steam boiler into normal operation phase, boiler fireman personnel to strengthen the boiler, instrumentation and safety accessories and auxiliary equipment is a monitor, a good job is a mobile inspection of boilers and auxiliary equipment running and timely completion of recording.

March 11, we learned from the Harbin municipal government: Harbin win the 2019 New Blue Sky Battle embodiments released this year, Harbin will be coal-fired pollution control, pollution discharge standards, high Vehicle emission control, comprehensive improvement of urban and rural non-point source, and prohibiting straw utilization as the main direction, precise Shi policy. Strive to the end, so that the sulfur dioxide, nitrogen oxide emissions are reduced by more than 17.6% in 2015 and 20%; concentration of PM2.5 decreased to 52 micrograms / cubic meter or so, and strive to 50 micrograms / cubic meter or less; and more severe reduce the number of pollution days to 21 days or less.

After the proposed scheme, Harbin bulk coal strengthen management and control, strengthening coal quality testing, to improve the sampling frequency. This year will develop clean heating embodiment, the priority development of the city urban central heating; central heating covered areas being difficult to accelerate the implementation of natural gas heating and electric heating, and other distributed clean heating. Unit embodiment "coal to clean energy" should be synchronized removal of coal-fired boiler, gas boiler need replacement after low NOx combustion technology, clean heating rate of 60% or more. City buses, taxis or car clean energy proportion of new energy and strive to reach 94% and 80%. Promote the use of gas vehicles to achieve the national emission standards for six. Six to stop selling below the country's gasoline and diesel. Establish responsibility dust control system, built-up areas prohibit the construction site mixing of concrete, mortar and use of bagged cement 9 city and county (city). Under the premise of protecting people's livelihood, heating boilers should be relatively conducive weather conditions during the pollutant dispersion from the oven, in the same area by different heating boiler early in the evening three periods of peak load shifting from the furnace.

Traps are generally installed in the what is the abc in boiler which position? Boiler traps role recently have several customers to inquire trap in which position the boiler, play what role do? The following content is explained and illustrated Hengyu energy equipment technician made against these two issues. Steam case of condensation to form water is condensed into water to remain in the original equipment or system will cause operation steam pipe water hammer or vibration, we run do not want it condenses into water, but the system related equipment into steam when there are a warm-up process, during preheating, the steam temperature above ambient temperature or above system-related equipment in case of condensation will form water, we will promptly take it sparse, this is what we often say hydrophobic role of discharging the water trap is to avoid or reduce the vapor-liquid two-phase, rapid cooling and flushing equipment, causing damage, vibration or the like. Natural circulation oven set came in the early start can enhance water drum, water wall of water cycle, in order to facilitate the analysis can also be attributed to the ranks of water drainage. But generally not so called. Some feed water pump also turn on the water pump warm, this logic I should go water drainage. , The heating system circuit is formed, to ensure continuous heating capacity of the heating system. The heating pipes, air heater, the level of hydrophobic plus the like. The general effect of the trap in order to prevent excessive pressure level variations into the same vessel hydrophobic or hydrophobic anti-channeling cause vibrations, which facilitate a slow, free expansion, such as a collecting box provided different hydrophobic side platoon expansion furnace according to different pressure levels, machine high accident hydrophobic expansion plus side, the body hydrophobic expansion and the like. If the pressure level deviation is too large hydrophobic into the same container, the container is required to have a large enough expansion space, ensure that the pressure after the expansion is still lower than the lowest pressure when the maximum hydrophobic sparse amount of water. Drainage systems connected to put a lot of water pipe (which are mostly consumer-pressure drainage, the main purpose is not to warm the pipe so do not consider the issue of expansion), turn on the water should pay particular attention to these! In practical operation, the discharge should be considered connected to the same pressure level in the water pipe water drainage, avoiding anti-channeling drainage, in particular of a pressure-dissipating system is isolated from the other systems do maintenance measures eliminate pressure isolation to prevent channeling anti-scald soda !

(1) open the door for emergency drain drum should be put to the normal water level water level shut down immediately.

(2) The steam temperature, the heated reducing or closing off the small door, door open and main steam superheater tubes hydrophobic hydrophobic gate.

3, when filled with water after treatment by drum water level continues to rise and exceeds the upper drum water level meter water level is visible on the need for emergency shutdown, as soon as possible with the main pipe splitting, immediately stop the water, recirculation door open, strengthen the case turn on the water boiler, and pay attention to upper water gauge steam drum water level appears to be put to the normal level after level off. After the normal Standby furnace to obtain technical staff agreed to perform the operation Stoke.

4, such as the water level in the steam drum water level tables invisible, not in time, should take the following measures:
