G4-73 and Y4-73 Boiler Ventilating, and Induced Draft fans
G4-73 and Y4-73 boiler ventilating and induced draft fans: are suitable for ventilating and induced draft fans of steam boilers below 670t/h in thermal power plants. The medium conveyed by the ventilator is air, and the maximum temperature shall not exceed 80°C; the medium conveyed by the induced draft fan is flue gas, and the maximum temperature shall not exceed 250°C. Before the induced draft fan, a dust removal device must be installed to minimize the dust content of the flue gas entering the fan.
Structural features
The fan is mainly composed of an impeller, casing, air inlet, regulating door, and transmission part.
(1) The impeller is welded by the obliquely cut blades of the backward-inclined wings. Due to the use of wing-shaped blades, the high efficiency, low noise, and high strength of the fan are guaranteed. The impeller is corrected by static and dynamic balance, so it runs smoothly.
(2) The casing is a spiral body welded with ordinary steel plates.
(3) The convergence and streamlined air inlet are made into an integral structure and fixed with the fan inlet side bolts.
(4) The adjusting door is a device used to adjust the flow of the fan and is installed axially in front of the fan.
The main shaft of the transmission part is made of high-quality steel, and the fan adopts rolling bearings. The bearing housing consists of an integral cylindrical bearing housing and a pillow bearing housing.

Company Profile
Zibo Hengding Fan Co., Ltd. Is located in Industrial Park, Beijiao Town, Zhoucun District, Zibo City, Shandong Province, China. The company covers an area of 12,000 square meters and a construction area of 8,000 square meters. The company has total assets of 27 million RMB and 186 employees, 46 engineers, and technicians. It has passed ISO9001 quality management system certification and has maintained long-term technical cooperation relationships with many colleges and universities, such as Xi'an Jiaotong University, Tianjin Nankai University, and so on. Now, it has developed into a modern ventilation equipment manufacturing enterprise with first-class testing and producing equipment, high-quality and excellent production molds, strong scientific research and development strength, a strict quality management system, and gradually perfected development. The company has 15 years of production experience, with an annual output of 10,000 sets of ventilators.
With the market demand as the development direction, the company has always adhered to independent R&D and continuous innovation. Now it has developed into a modern environmental protection, and ventilation equipment enterprise, which mainly consists of mine fans, coal mine ventilators, and centrifugal ventilators. There are more than 50 series of ventilator products with more than 600 specification models, widely used in many industries, such as mines, coal mines, oil fields, chemical industry, kilns, metallurgy, boiler, textile and building materials, etc. The company's products are sold continuously with reliability in 29 provinces, cities, and autonomous regions of China, as well as Vietnam, Indonesia, Russia, Serbia, Pakistan, Kazakhstan, Tajikistan, Iraq, Saudi Arabia, and other countries.
Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience
Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.
The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
Quality assurance measures:
In long-term production management, our company has formed a set of standardized process control measures and control points, which can provide users with high-quality products in all directions. Our company has a good reputation and is an enterprise that users can absolutely trust.
Our company has obtained the IS09001 certification from the International Organization for Standardization (see Enterprise Qualification Materials for details). We strictly standardize the operation process and control points of product manufacturing
After Sales Service
When the equipment of the buyer is installed, our company is responsible for on-site installation guidance, personnel training and commissioning of test-drive, The separately purchased fan accessories can be used for telephone connection guidance and debugging
Our company guarantees that the structural safety, aerodynamic performance, running noise, and appearance, quality of the supplied ventilators can be checked and accepted by relevant departments.
The quality assurance period for the supplied ventilator equipment, except for special provisions, is 18 months from the final acceptance of the ventilator; The warranty period for the individual parts of the fan is 6 months.
Before the expiration of the warranty period, if a problem with ventilator equipment occurs due to the manufacturing quality of our company, our company is responsible for free repair and replacement; if the problem is caused by the buyer, our company will also repair and replace it in time, and only charge its cost. ;
