Descriptions

Suitable for asphalt plant drying drum processes, the burner can use coal, oil, and gas as fuel;
Based on the existing technical accumulation of coal combustion, combined with oil and gas combustion technology, the newly developed burner can perform coal powder combustion, oil/gas combustion, and mixed combustion of the two fuels;
Four combinations of coal powder, kerosene, coal gas, and kerosene gas are available. Coal, oil, and gas combustion do not reduce the combustion performance of the original fuels;
Coal powder, oil, and gas burners are all automatically controlled, with one-button start/stop, remote monitoring, and fault alarm and diagnostic functions;
Based on the technical characteristics of coal powder combustion, through staged fuel combustion and staged air supply, more complete and stable coal powder combustion is achieved;
The newly designed flame tube adopts a three-stage air supply structure. The primary air duct separates the high-concentration air-powder mixture, the secondary air is a high-intensity swirl air, which swirls the coal powder into the central recirculation zone, where it mixes thoroughly with the internal air, effectively preventing the coal powder from spreading outward too quickly. The tertiary air is a straight-through air, providing sufficient air for coal powder combustion, ensuring complete combustion. A cooling air duct is set on the outside of the flame tube to reduce the flame tube temperature and improve its service life;
The self-developed coal powder feeding and metering system can achieve a higher coal powder combustion adjustment ratio, and has the functions of instantaneous coal powder flow rate and cumulative usage, and can realize two control modes of frequency control and quantitative control of coal powder supply, achieving the purpose of precise control of coal consumption;
The enclosed coal powder storage tank is isolated from the outside atmosphere under normal conditions, and is equipped with a explosion-proof door, safety valve, manhole, silo top dust collector, level detection, temperature detection, cone-type arch breaker, and nitrogen protection system, etc. The coal powder tank intelligent control system can realize one-button start/stop of powdering, intelligently monitors the temperature and level in the tank, realizes the automatic nitrogen protection function of the system, and the unique arch-breaking structure design ensures continuous and stable coal powder supply, providing multi-faceted protection for safe and stable production;
The automatic nitrogen supply device is designed and developed according to the nitrogen protection process of the coal powder tank, with a large capacity of nitrogen generation and storage, providing sufficient nitrogen for the safety protection of the coal powder tank;
The oil type uses advanced low-pressure medium atomizing spray guns for complete and efficient oil combustion, saving energy and protecting the environment;
The gas type uses tubular fan-shaped nozzles for thorough mixing and high combustion efficiency;
High-voltage electronic ignition, independent gas (propane, acetylene, liquefied gas) ignition guns, automatic ignition;
Intelligent electronic proportional adjustment of fuel and air volume, frequency conversion automatic control, high control and adjustment accuracy, more complete combustion;
