Product Introduction

Basic Principle Of Wood Chip Burner: Feeding feedstock into the furnace by even feeding，high temperature pyrolysis suspension semi-gasification combustion，then transfer the heat to the energy-using equipment. Using the principle of radiant heat and convection heat，three-stage air increasing to make wood chip fully burned in the furnace, more than 85% of the heat is transferred to energy-using equipment.

Feedstock Of Wood Chip Burner
Fuel type: wood chips, pellets,bamboo chopsticks, building templates, Chinese medicine residue, etc
Size:<10cm
Moisture content: <15%

Wood Chip Burner Application: Used for Steam boiler, Thermal oil furnace, Rotary dryer, Spray drying line, Coal-fired boiler, Aluminum melting furnace, Incinerator, Forging heating

Remark: The above parameters are calculated according to 10 tons boiler. The actual price of raw materials is based on the actual local price. The data in the figure shows that biomass fuel can save more than 70% cost than natural gas, and it has environmental advantages over coal.

Features Of Wood Chip Burner

  • Our company has a complete range of equipment with a heat capacity of 300,000-12,000,000 Kcal/h, matched boiler of 0.5 to 20 tons.
  • Safe automatic feeding, automatic alarm switching function.
  • Large-medium-low fire can be automatically switched by operating conditions.
  • One-button to start, safe automatic ignition.
  • Manual-automatic switching, can adapt different operating conditions.
  • Full body cast first grade high alumina refractories，The host adopts 4 layers of protective measures, and the whole body is cooled by water.Professional refractory casting technology, anchor nail reinforcement, reasonable expansion joint technology.
  • The top of the furnace is protected by four layers of U.S. refractories and covered with water-cooled insulation.
  • Nozzle imported high aluminum material, anti-corrosion high temperature resistance。
  • The outer water jacket protects the furnace , reduce surface of furnace temperature and fully protects the furnace body.
  • The main body adopts three-layer insulation, with less heat loss and improved thermal efficiency.
  • High-temperature pyrolysis Multi-stage votex oxygen ensures that the raw material is fully burned and the thermal efficiency is improved.
  • Suspension fluid combustion, increase the contact area with oxygen, so that the fuel combustion is fully uniform, the overall thermal efficiency is up to over 95%.
  • The furnace front and furnace back system can realize interconnection interlocking, explosion-proof combustion and anti-tempering.
  • Micro-negative pressure system operation, simple operation on duty.
  • The furnace body is equipped with a thermometer, and the temperature of the furnace body can be observed at any time to avoid high temperature damage to the furnace body and the risk of burns to the operator.
  • Biomass fuel has low cost, automatic control saved labor cost, and high-tech design with more efficiency, comprehensive energy-saving effect is obvious.
  • Meet environmental standards, biomass fuel emissions are almost zero pollution, sulfur dioxide and nitrogen oxides are much lower than the national emission standards.
  • The cost of recovery is fast, tens of thousands of dollars invested, and millions of dollors are saved per year.
