Rotary kiln burner: Long combustion flame, high temperature resistance, and long service life

The natural gas rotary kiln burner is also called the natural gas rotary kiln burner, spray gun and torch. Its fuel is: natural gas, English name (NG). Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. adopts the flame stabilizing disk structure in the structure and design of the natural gas burner, and the external mixed combustion mode ensures the reliability of the design. In the process of supporting the rotary kiln equipment, according to the requirements of the fluidized bed furnace structure, flame length and material burning process, Targeted improvement of burner structure and installation method.

The design of the natural gas rotary kiln burner control system is very important. The natural gas burner control system draws on the design concepts and experience of excellent domestic and foreign manufacturers, and is equipped with automatic ignition, flameout alarm, emergency gas cut-off, leakage alarm, and high and low pressure cut-off functions for gas pipelines. The local control cabinet reserves communication ports, which can be connected to the user's central control room, achieving local and remote control functions.

The characteristics of the rotary kiln burner designed by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. are as follows:

1. Structural characteristics of rotary kiln burner. The rotary kiln burner designed by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. adopts a stable flame disc structure. The angle of the stable flame disc air hole can achieve the rotational flow of air, enhance the full mixing with the gas jet, and achieve stable and full combustion. This is the step to achieve energy saving for the rotary kiln burner, and the structural design is reasonable.

2. Material structure of rotary kiln burner. The material of the combustion tube of the rotary kiln burner determines its service life. Zhongwei Company adopts a high-temperature resistant material "double sleeve" structure or water-cooled heat dissipation, high-temperature resistant pouring material, and the material selection is stainless steel 310s (Cr25Ni20) outer tube with the same material protection sleeve or high-temperature resistant pouring material. It can withstand high temperatures of 1100-1400 ℃, with a service life of more than 5 years and low maintenance costs.

The length of the combustion tube extending into the cylinder is about 1.5 to 3 meters, which can be extended according to actual working conditions. The flame length is about 3.5 to 9 meters, which can be adjusted online to extend the length of the high-temperature zone. The material is prolonged during the high-temperature period, and the calcination temperature is uniform, reducing the temperature difference between the material surface and the core.

3. Rotary kiln burners can be divided into gas rotary kiln burners and oil rotary kiln burners based on fuel. Gas burners are divided into natural gas rotary kiln burners, blast furnace gas rotary kiln burners, coke oven gas rotary kiln burners, converter gas rotary kiln burners, yellow phosphorus tail gas rotary kiln burners, and light hydrocarbon gas rotary kiln burners. Fuel oil burners are divided into: diesel rotary kiln burners, heavy oil rotary kiln burners, and environmentally friendly oil (boiler oil burning fire oil) rotary kiln burners. Multi channel coal powder burners can be further divided into gas mixed combustion burners, oil gas mixed combustion burners, gas gas mixed combustion burners, etc.

4. The fully automatic control system of the rotary kiln equipment has achieved the "intelligence" of calcined materials, achieving the production goal of reducing consumption and increasing production. For more details, please call (WeChat synchronization): 15713691937.

Zhengzhou Zhongweihuan Environmental Protection Equipment Co., Ltd. undertook the automation control engineering project of rotary kiln equipment, and designed, integrated and constructed the whole control scheme from "feeding to dedusting". Try to reduce labor costs as much as possible and achieve "intelligence" of rotary kiln equipment.

5. A 'package' solution for gas equipment. For remote areas without gas pipelines, Zhongwei Environmental Protection undertakes pipeline design and construction projects, including LNG storage tanks. Zhongwei has professional design and construction qualifications to ensure project quality.

Zhongwei Environmental Protection Group Co., Ltd. (Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. and Zhengzhou Deste Automation Equipment Co., Ltd.) undertakes the "general contracting" project of large-scale gas and oil fired kilns, automation control systems, desulfurization and denitrification equipment, kiln refractory material masonry, and online monitoring devices both domestically and internationally. It is a "one-stop" environmental protection kiln solution provider and implementer.
