DZL series hot selling vertical type steam boiler

Thermal efficiency and fire the boiler with a boiler efficiency of how to enhance the long-term course of their work, some of its parts will be some failures, which requires the relevant staff on a regular basis of its examination, so it will not affect the work of the boiler effectiveness. Also note that regular maintenance of the boiler, so as to improve the thermal efficiency of the boiler efficiency and the use of fire. Supporting domestic heating boiler feed, Fan efficiency is about 85%, with the heating boiler supporting GC boiler feed pump efficiency of 40% to 62%. And GC type commonly used to pump efficiency at 47% to 48% or less, indicating delivery, the lead fan efficiency, especially for pump efficiency is not high, great energy saving potential. Domestic manufacturing pumps and fans continue to produce some of the delivery of energy-efficient boiler, induced draft fan and feed pump. For example, suitable for 2 ~ 20t / h boiler supporting 5-48 series fans, the best total pressure efficiency up to 87.5%, energy-saving effect is obvious. For the current low in use efficiency, energy consumption of delivery, induced draft fan and feed pump, should improve the efficiency of technological transformation through various means or replacing new and efficient products. The new design of the boiler room should try to use energy-efficient delivery, induced draft fan and feed pump, supporting reasonable auxiliary boiler. So as to effectively reduce the power consumption of auxiliary boilers, improving the net efficiency of the boiler. Improve the efficiency of the boiler with fire, smoke and heat in addition to try to reduce exergy loss, so that the fuel combustion, the major measures to reduce the exergy loss in the furnace, i.e., combustion and heat transfer processes exergy destruction. Combustion process things with fire damage is due to the burning uncontrolled chemical energy into heat caused. The only feasible measures to minimize this damage by fire is to increase the combustion temperature. The main pathway is reduced heat transfer process irreversible exergy loss is to increase the average temperature of the working fluid absorbs heat. The working fluid in a dzl series hot selling vertical type steam boiler heat absorption, the liquid to go through a phase change to the gaseous state. In the phase transition, the working fluid temperature and pressure have strict constraints, I need to raise the temperature of this phase will have to simultaneously increase the pressure. Working fluid temperature and elevated pressure, will increase the average temperature of the working fluid absorbs heat, the fire 1KG steam with the value increase, of course, also marks improve the taste of steam, thereby increasing the fire boilers with efficiency.

Third, automation

With the deepening of modern gas boiler technology and improve, has been able to fully meet the requirements of automated operations, we have been able to better meet the automation requirements on the ignition off and other related content, on the one hand greatly improve the safety in production processes, and the other On the one hand greatly reduces manpower costs. Powerful automation further meet the needs of a modern and efficient intelligent production enterprises.

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.

Related calculations boiler which standards need to refer to? Computing standards related to boiler there are many, mainly refers to the calculation of boiler design process need to make, which also includes two parts People's Republic of China national standards and national GB standard People's Republic of China Ministry of Machinery Industry Ministry JB, and, with the boiler technology the continuous development of boiler standards to be followed are times, however, there are still standards in 2003 even before the application, because the demand is still consistent with the current boiler design, production. The following is a brief example: "Steam Boiler Safety Technology Supervision", "industrial boilers General", "thermal test specification industrial boiler", GB / T16508 "boiler pressure boiler shell element intensity calculating", GB1576-1996 "low pressure boiler water quality standards ", DB11 / 109-2014" boiler air pollution emission standards ", GB13271-91 People's Republic of China environmental standards, BJ27-96" industrial boiler installation construction and acceptance "," shell boiler pressure element intensity calculation "" dzl series hot selling vertical type steam boiler safety technology supervision "," boiler room design specifications "," industrial thermal boiler test specifications, "" low-pressure boiler water quality "and so on.
