Burner Nozzles

Shandong Qishuai Wear-Resistant Equipment Co., Ltd. has established itself as a leader in the wear-resistant equipment sector. Our burner nozzles have garnered significant market recognition for their exceptional quality and outstanding performance. Leveraging a specialised technical team and mature production processes, the company supplies premium burner nozzles to diverse industries, enabling enterprises to achieve efficient and environmentally sound combustion operations. Whether delivering stable thermal energy in large industrial boilers or supporting high-efficiency power generation in electrical equipment, the performance of burner nozzles directly determines combustion efficiency, energy utilisation rates, and pollutant emission levels.

Advanced materials, forging extraordinary performance

The burner nozzles manufactured by Shandong Qishuai Wear-Resistant Equipment Co., Ltd. are crafted from premium high-temperature resistant and corrosion-resistant materials. Among these, silicon carbide stands as the ideal choice for burner nozzles owing to its exceptional hardness, low thermal expansion coefficient, and outstanding oxidation resistance, rendering it particularly suitable for high-temperature environments.

Materials using alumina ceramics appear commonly in producing components for burner nozzles. These materials provide high levels of hardness and resistance to wear and corrosion. The hardness measures from HRA80 to HRA90, and this level allows the materials to resist damage that occurs from flows of gas at high velocity and from matter in particulate form during processes of combustion. The ceramics also show strong stability in chemical conditions, and this stability allows the structure to remain intact when exposure occurs to substances that corrode, such as materials that are acids or alkalis. This feature increases the time that components for burners continue to function. For conditions that require particular considerations of cost and performance, the components use stainless steel. The grades 304 and 309 of stainless steel provide properties that allow function in conditions with moderate temperature levels and in environments that contain elements that produce corrosive effects, and these materials address different requirements that clients present.

Adaptable to diverse operating conditions

To address the varying combustion requirements across diverse industrial applications, the burner nozzles from Shandong Qishuai Wear-Resistant Equipment Co., Ltd. feature precise adjustment capabilities. Through dedicated control mechanisms, the injection volume and ratio of fuel and air can be readily modified to accommodate different combustion conditions. Whether delivering substantial thermal output during high-load operation or maintaining precise temperature control under low-load conditions, these nozzles ensure stable performance, guaranteeing both the reliability and efficiency of the combustion process.

The analysis uses industrial boilers to show the approach. During the phase when the system starts, the nozzle that provides fuel allows adjustment to deliver fuel and air at a ratio that is lower and this occurs in a manner that is gradual. This approach allows ignition to occur in a manner that is smooth. During operation that follows in normal conditions, the rates of flow and the ratios between fuel and air show adjustment that is flexible. This adjustment relates to requirements for load in the boiler and this allows operation that is efficient. During the phase of shutdown, the supply of fuel and air shows reduction that is progressive. This allows cessation to occur in a manner that is safe. The capability for adjustment that is precise allows nozzles that provide fuel to show application that is wide. This application occurs across sectors in industry that are diverse. These sectors include generation of power, processing in chemical industry, and materials for building. The nozzles provide solutions that are reliable. These solutions relate to requirements for combustion and these requirements occur across industries that are various.

Unique Design

Anti-clogging design for extended service life

The burner nozzles from Shandong Qishuai Wear-Resistant Equipment Co., Ltd. provide a design that addresses blockage issues. This design resolves problems that occur in nozzles. The internal structure shows careful development. It includes passages for fuel that allow smooth flow. These passages reduce the rate at which impurities attach to surfaces in the fuel stream. The design also limits accumulation of materials within the passages. The outlet of the nozzle demonstrates particular features in its design. The outlet uses specific shaping based on geometric principles and control of dimensions. This approach produces fuel leaving at velocity and angle that remain uniform across the outlet. The uniform pattern prevents blockages that develop when flow rates decrease in certain areas of the outlet.

Structural Optimisation for Enhanced Combustion Efficiency

To further elevate combustion efficiency, Shandong Qishuai has undertaken profound structural refinement of the burner nozzle. The nozzle incorporates an advanced swirl design internally, generating a powerful rotating airflow during fuel ejection. This ensures thorough mixing with air, increasing homogeneity and contact surface area, thereby enabling faster and more complete fuel combustion. Concurrently, precise adjustments to parameters such as spray angle and flow distribution achieve an optimal fuel-to-air ratio.
