saudi arabia anthracite coal fired hot water boiler
Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard [1993] No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial steam boiler parameters Series" and GB3166-82 "saudi arabia anthracite coal fired hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."
The boiler is capable of utilizing coal, oil, gas, electricity can be transmitted to the chemical medium, the pressure vessel is converted to thermal energy or mechanical energy, has been widely used, saudi arabia anthracite coal fired hot water boilers and heating in industrial production is common to provide power type. Hot water boiler fuel can be utilized to heat the water to a certain temperature, or for heating domestic hot water.
Steam boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.
June 22, 2018 in the evening around 6:40, Chongqing Hechuan keel village "Ding taste the food factory" boiler exploded, the accident killed two people, three people were injured.
At the scene, boiler room Zhata, damaged boiler flew ten meters outside the field, next to a few factories are subject to different degrees of damage, around the ruins. But because not many nearby residents, no adverse impacts to other villagers.
According food factory owner friends when the accident occurred, both inside and outside the boiler room just five people. One person was killed and four people were injured, one of whom died en route to hospital, the other three in stable condition and is currently being treated in. It is understood, Ding taste the food factory is a small tofu factory, usually only a few factory workers. When the accident occurred, it is time off work, the boss's father, Huang uncle went to the boiler room, prepare a little help, but I do not know which part of improper operation, resulting in an explosion.
The boiler explosion, resulting in serious consequences and impact, but also sounded a warning for the steam boiler is using various food processing plants. Steam boiler output to high-temperature steam, with a certain risk, in use, to operate in strict accordance with the provisions, not miss any details, nor allow non-professional staff stoker boiler operation to avoid unnecessary losses.
1, boiler factory should be accompanied by "technical safety specifications of the design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision and inspection certificate performance)."
2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction.
3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit of Special Equipment To Quality and Technical Supervision, Inspection and declared the boiler installation supervisory inspection and hydrostatic testing. After passing by the Quality and Technical Supervision, Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance.
4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form" to the Quality and Technical Supervision registered, and obtain a "safe use of special equipment registration certificate" .
5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record.
6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories.
