Zhongwei ZWKB Types of energy-saving dryer burners include:

Dryer burner basis Fuel type classification includes: gas burners, oil burners, and pulverized coal burners; single fuel or multi-fuel mixed burners, with specific types detailed as follows:

Gas burner : natural gas, petroleum liquefied gas, propane gas, blast furnace gas, converter gas, coke oven gas, yellow phosphorus tail gas, blue carbon tail gas, carbon black tail gas, mineral furnace gas, biomass gas, cracking gas, and mixed gas from gasifiers, etc.

Oil fuel : diesel, heavy oil, methanol, waste oil, coal tar, etc.

Pulverized coal fuel

1. Characteristics of gas burners

( 1 ) High-efficiency heat conversion

Achieves high-efficiency heat conversion through premixed air and fuel, significantly reducing fuel operating costs.

( 2 ) Multiple combustion control schemes

According to combustion control methods, it can be divided into single-stage fire, two-stage fire, and proportional adjustment types. The proportional adjustment type can precisely regulate gas and combustion air flow, dynamically adjusting according to different operating conditions to achieve energy saving.

( 3 ) Strong fuel adaptability

Can adapt to gas, oil, pulverized coal, and even special fuels such as rice husk, bran, bamboo powder, etc. Designed as single fuel or multi-fuel mixed burners for oil, coal, and gas, enabling automatic switching between different fuel combustions.

( 4 ) Complete safety protection system

Equipped with low-pressure safety valves, leak detection solenoid valves, and sensors. All safety protection measures are interlocked to ensure stable, reliable, and safe operation of burner equipment.

( 5 ) Energy saving and environmental protection

By automatically adjusting primary air distribution (automatically adjusting air volume when gas pressure fluctuates), combustion is sufficient and thermal efficiency is high, while reducing NOx pollutant emissions.

( 6 ) Structure and maintenance

Split design (separating combustion system and air supply system) for easy maintenance; regular inspection of main gas source regulating valves, filters, and control valve sensitivity is required.

2. Main characteristics of oil burners include

( 1 ) High thermal efficiency

Oil burners automatically adjust primary air distribution (automatically adjusting air volume when fuel pressure fluctuates) to ensure sufficient mixing and combustion of oil fuel, reducing black smoke emissions and improving oil combustion efficiency.

( 2 ) Structural characteristics

Atomization methods: divided into mechanical and medium atomization. The former achieves atomization through mechanical impact, while the latter relies on steam or compressed air to assist atomization.

Control system: uses a high-pressure electronic ignition system combined with a photoresistor for real-time flame monitoring, achieving fully automatic operation. When using special fuels such as heavy oil, tire waste oil, or coal tar, due to their high viscosity, poor fluidity, and mechanical impurities, direct mixing with combustion air is difficult. Measures such as dehydration, filtration, and auxiliary heating are taken to improve fuel fluidity. High-pressure atomizing medium efficiently mixes oil droplets with combustion air, enhancing atomization combustion efficiency for maximum efficient and complete combustion.

3. Pulverized coal burners have the following main characteristics

Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. has two types of pulverized coal burner structures: ordinary pulverized coal burners (as shown below), complete sets include coal feeders, pulverized coal pipes, combustion air fans, etc. The main features of this type of pulverized coal burner are safety, economy, practicality, and high cost performance; widely used in drying fields such as river sand, sludge, compound fertilizer, and other materials, matched with afterburner or hot air furnace equipment to achieve efficient combustion.

( 1 ) High-efficiency combustion

Pulverized coal stays longer in the high-temperature zone of the burner, resulting in high combustion efficiency. Flue gas emissions appear as steam-like white smoke with no black smoke pollution.

( 2 ) Fast ignition and heating

Natural gas or diesel fuel can be used to ignite pulverized coal automatically or manually, making ignition easy and heating fast, significantly improving work efficiency.

( 3 ) Flexible adjustment

Air supply volume and coal input can be changed as needed; furnace temperature and flame length can be adjusted within a wide range.

( 4 ) Strong adaptability

Wide applicability of coal types, high thermal efficiency, and shortened temperature rise time during heating.

( 5 ) Energy saving and environmental protection

Low dust emissions, NOx reduced generation, and decreased ash accumulation in the tail flue.

Based on the above fuel characteristics, our company professionally designs single fuel or multi-fuel mixed burners using oxygen-enriched and pure oxygen air combustion methods to achieve energy saving, high output, and low nitrogen emissions.

Currently, our company offers three types of pulverized coal burners: one is the conventional coal feeder, which meets most customer site needs and is simple to operate; the second is a customized pulverized coal burner designed specifically for customers with a "one kiln, one design" approach; the third is a multi-channel pulverized coal burner (generally suitable for long flames).
