China thermic fluid boiler

Rear of the china thermic fluid boiler deposition of combustible material, re-ignition combustion phenomenon known as secondary combustion. The occurrence of secondary combustion boiler, will economizer, Fan burned, when severe may also totally destroyed the rear of the boiler.

June 22, 2018 in the evening around 6:40, Chongqing Hechuan keel village "Ding taste the food factory" china thermic fluid 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.

One inherent feature of a CFB water china thermic fluid boiler is its insensitivity to variations in fuel composition.In many cases, coal or brown coal from the same mine varies widely in terms of heat value, ash content, and moisture. Such variations do not materially affect the combustion temperature, due to the thermal wheel that the circulating solids create, i.e. the solids act as a buffer against any variations in fuel characteristics andthe amount of fuel present in the unit is only a few percent of the total amount of bed material.The relatively uniform combustion temperature provided by the CFB results in a uniform heat flux and even temperatures in the boiler tubes.

Noise which (1) heat exchange noise appears condensing gas china thermic fluid boiler work: condensing gas boiler water vaporization occurs if the local phase transformation during heating, so that the flow state change trigger Oscillation heat exchange noise. (2) Aerodynamic noise: eddy current occurs when the flowing gas condensing gas boiler (gas, air, flue gas), the pressure generating mutation, or cut the flow direction of air turbulence caused by a mutation (a pressure wave), the air will produce dynamic noise. (3) mechanical noise: it is the vibration generated due to the solid. On condensing gas boiler, the fan impeller rotates, the housing will lead to vibration and mechanical noise. (4) combustion noise: a laminar, turbulent combustion flame noise and oscillation noise. (5) flame noise: This phenomenon occurs in the sudden closing the gas valve, flame goes along with noise generated, noise can be used as the tempering flame gas noise is zero, is a special form of tempering. (6) Tempering noise: is the fire hole flame retraction cavity burner a combustible gas mixture to ignite acoustic deflagration initiated. (7) an ignition noise: is the deflagration caused by the ignition. Different noise condensing gas boiler caused by different reasons, many failures can be distinguished from noise. Overall, the noise condensing gas boiler is not large, if the noise is caused by the failure to timely troubleshooting.
