Low nitrogen natural gas rotary kiln burner: desulfurization

1、 Introduction and classification of rotary kiln burners: Rotary kiln burners, also known as rotary kiln burners, are important devices for injecting fuel into the kiln, injecting gas, fuel oil, or coal powder. After sufficient combustion, they generate a large amount of heat and are used for calcination or drying of materials.

Classification of rotary kiln burners:

Rotary kiln refers to a rotary calcination kiln (commonly known as a rotary kiln), which belongs to the category of building materials and equipment. Rotary kilns are divided into cement kilns, metallurgical and chemical kilns, lime kilns, ceramic sand kilns, and oxidized pellet kilns for calcination materials according to different processing materials.

1. Rotary kilns can be divided into cement rotary kilns, ceramic sand rotary kilns, kaolin rotary kilns, lime rotary kilns, etc. according to their uses.

2. Rotary kilns are divided into gas rotary kiln burners, coal powder rotary kiln burners, and oil rotary kiln burners based on the different heat sources adopted by the burner. Among them, gas rotary kiln burners are divided into: natural gas rotary kiln burners, coke oven gas rotary kiln burners, blast furnace gas rotary kiln burners, gas producer gas rotary kiln burners, converter gas rotary kiln burners, light hydrocarbon gas rotary kiln burners, etc. Oil rotary kiln burners are divided into: diesel rotary kiln burners, heavy oil rotary kiln burners, methanol rotary kiln burners, and alcohol based fuel environmentally friendly oil rotary kiln burners.

3. Coal powder burners are classified as multi-channel coal powder burners, gas mixed combustion burners, gas mixed combustion burners, oil gas mixed combustion burners, etc.

2、 The characteristics of the low nitrogen natural gas rotary kiln burner and control system are:

As the "heart" of building materials enterprises, the importance of rotary kilns can be imagined. The rotary kiln burner can be said to be the "heart" of the heart

Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd., as a manufacturer of large-scale rotary kiln burners and industrial kiln burners in China, has many years of practical experience. Zhongwei rotary kiln burners have registered the trademark "Shenzhihuo" brand, and have a certain level of popularity in China. The characteristics include the following four aspects:

1. The length of the rotary kiln nozzle penetrating into the kiln is relatively long, usually between 1500mm-4000mm. Depending on the calcination production process and output of the rotary kiln, it is designed with a hanging or ground rail type mobile cart to facilitate adjustment of the length of the burner penetrating into the kiln and maintenance.

2. The combustion tube of the rotary kiln burner is made of high-temperature resistant alloy material or externally poured high-temperature resistant castable structure, with secondary protection measures, which not only extends its service life but also resists harsh high-temperature environments.

3. Protective measures are in place for the rotary kiln burner. The design of the rotary kiln burner control cabinet includes automatic ignition, flameout protection, leakage protection, and pressure protection. According to the material calcination process, automatic temperature control functions can be achieved. The connection between the local control cabinet and the central control room can achieve local and remote or mobile control functions.

4. The automatic temperature control system has powerful functions, and the rotary kiln burner is equipped with wireless temperature measurement (or infrared thermometer), achieving accurate temperature control in production, ensuring the quality of the rotary kiln material calcination, and meeting the needs of the production process.

5. The rotary kiln equipment achieves low or ultra-low nitrogen emissions by improving the burner and adopting SCR or SNCR denitrification technology, meeting higher environmental protection requirements.

3、 For large-scale rotary kiln equipment, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. mainly provides the following services:

1. Design and manufacture rotary kiln burners, and be responsible for installation, commissioning, and training services.

2. Integrate the automation control system of rotary kiln equipment, undertake workshop and entire factory automation control system engineering projects.

3. Low nitrogen technology renovation project for rotary kiln equipment, "general contracting" project for desulfurization and denitrification equipment and online monitoring device.

4. For refractory or casting material masonry engineering, design and construction engineering in the rotary kiln, please call (WeChat synchronization): 15713691937 for details.

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.
