high quality vulcanizing boiler

4 tph WNS gas-fired fire tube high quality vulcanizing boiler project for dairy industryAs the key device in the production line of dairy industry, a steam boiler provides a plenty of steam for many production processes including distilling, disinfecting and sterilizing; a high-performance steam boiler has a direct impact on the product quality. Guangxi Shibu Dairy Industry Co., Ltd., established in 1995, has been developed into a large modern dairy enterprise mainly producing dairy products. To meet the increasing market demands, Shibu Dairy has introduced 28 domestic and international production lines as well as building a well-organized milk source base and a cold chain transportation system of fresh milk. A steam boiler plays a significant part in the production line; therefore, Shibu Dairy treated the purchase of the steam boiler as the top priority, they held a large-scale public bidding all over the country to seek the high efficient and environmentally friendly gas-fired boiler. ZOZEN successfully won the bid with its premium products and systematic solutions and provided them with 2 sets of WNS gas-fired steam boilers (WNS4-1.25-Q). This series of boiler adopts a large-diameter corrugated furnace to increase furnace heat transfer area, ensuring the stable running of the boilers. In addition, the boiler is equipped with a low NOx burner to reduce the NOx emission; furthermore, ZOZEN also installed economizer and condenser on the tail of the gas-fired boiler, which will effectively improve the thermal efficiency up to 98%.

Problem analysis of the deformation of the heating surface of the steam high quality vulcanizing boiler 1, the heating surface modification phenomenon a. Waterwall tubes or deformation of the door to see the fire door from the saw, when accompanied by water, can see the red curved water wall tube. B of the horizontal combustion furnace of the boiler, can be seen from the observation hole furnace wall to the fire front side of the deformation. 2. Heating Surface modification of a. Serious boiler water, heating surface of the cooling pot of water had to be thermally deformed. b. poor design structure. The local circulation flow rate is too low, stagnation, that the wall temperature exceeds the allowable temperature deformation. c. Install error, the pressure receiving member is not free to expand. D. substandard quality, thick scale, excessive water residue.

Considerations when using a gas steam high quality vulcanizing boiler steam boiler proper use of gas to ensure safe operation of the gas steam boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public enterprises and businesses, it is dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by "technical safety specifications of the design documents boiler factory, product quality certification, safety and 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 To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State 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", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 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. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.
