Chip Burner FAQs

DATE: 21-12-05
  • What types of biomass semi-gasification wood chip burners are available, and how are they distinguished?

A: The models of this type of equipment range from HQ-LM0.5 to HQ-LM20.0, and the corresponding calorific value is 300,000 kcal/h to 12 million kcal/h.

There are two types of model distinction: one is according to the model 0.5 to 20.0 corresponding to 0.5 tons to 20 tons of boiler models; the other is based on the calorific value of 300,000-12 million kcal/h, every 600,000 kcal can be divided into a model. See an example in the table below:

model HQ-LM0.5 HQ-LM1.0 HQ-LM2.0 HQ-LM3.0 HQ-LM20.0
Calorific value (kcal/h) 30w 60w 120w 180w 1200w
Rated fuel consumption (kg/h) 75 150 300 450 3000
Docking boiler (ton) 0.5 1 2 3 20
The fuel takes wood chips as an example, the calorific value is 4000kcal/kg, and the water content is less than 15%


  • Why does the furnace body of the biomass semi-gasification wood chip burner need to be cooled, will there be heat loss, and the difference between water cooling and air cooling?

Because the inside of the burner furnace is high temperature combustion, the temperature of the continuous working furnace body will gradually rise. If the furnace body temperature is too high, the refractory material and the main steel plate will be damaged. Therefore, it is necessary to take measures to cool the furnace body, which can greatly extend the service life of the equipment.


Cooling will use a certain amount of heat loss, but the advantages outweigh the disadvantages compared to prolonging the service life of the furnace body and reducing the failure rate.


The specific heat capacity of water is the largest, and it is the best medium for cooling. The technical requirements for furnace body welding are relatively high, the specific heat capacity of air is small, and the cooling effect is poor. It can be used for small equipment within 300,000 kcal, but The continuous industrial application of large-scale equipment has poor air cooling effect, which affects the service life of the furnace body.


  • Is the biomass semi-gasification wood chip burner easy to operate? What is the style of the control system?

Our equipment control system is divided into two types: semi-automatic and fully automatic.

There are not many control points of the equipment, just control the feeding and air distribution, and we have professional guidance installation and debugging personnel, responsible for free training for customers, simple and easy to understand, generally 3-5 hours to master.


  • How many years can the biomass semi-gasified wood chip combustion function be guaranteed?

The designed service life of this type of equipment is more than 8 years. According to the feedback from the company’s old customers, the equipment has been used for more than 10 years. Our company provides one-year free after-sales service for the whole equipment and lifelong equipment maintenance guidance. After a third-party appraisal, the equipment does not meet the corresponding technical parameters of the contract calibration, and it can be refunded and returned.


  • Is biomass semi-gasification wood chip burner expensive to use?

The calorific value of wood chips is about 4000 kcal/kg. The heat generated by 2.5kg of wood chips after full combustion is equivalent to 1m³ of natural heat. The purchase price of wood chips is generally 400 yuan/ton, that is, 2.5kg*0.4 yuan/kg=1 yuan. The price is about 3.5 yuan/m³, so it can save 70% compared to natural gas. A 10-ton boiler uses about 15,000m³ of gas a day (24-hour operation), and the cost of using natural gas is 52,500 yuan. If it saves 70%, it will save 36,750 yuan per day. Working for 10 months a year can save 11 million yuan. The investment of 300,000 yuan for 10 tons of this type of equipment can recover the cost within 10 days.


  • The installation space of old equipment retrofit equipment is limited, can it be customized according to the space?

We can adjust the direction of the feeder and air box for this type of equipment, and can be designed individually according to the customer’s site space, and the design fee is waived.


  • What are the main advantages of your company’s equipment compared with other manufacturers?

Our company has been established for more than 20 years and has been engaged in this business. The quality of equipment and high-quality service are our foundation, and we never blindly ignore the quality of equipment for the sake of sales.


The company has a professional technical team to provide customers with high-quality pre-sale planning and design and after-sale professional technical guidance. We are not only proficient in the operation and maintenance of our equipment, but also proficient in the entire system of customer energy-using equipment. We know our company well The equipment is only the engine in the customer’s complete set of energy-consuming equipment. The normal operation of the system requires the entire chain to operate efficiently in order to operate efficiently. Some colleagues may not fully grasp the company’s equipment, so how can we help customers solve system problems.


Our company has a professional after-sales guidance operation and maintenance team and strong after-sales capabilities. We have always pursued zero and unplanned after-sales, so we insist on the quality of our equipment, but it does not mean that we have no ability to after-sales. On the contrary, our after-sales are all Engineers with more than 5 years of installation and debugging experience can provide more accurate and timely services. More than 80% of companies in the same industry do not have dedicated after-sales teams.


Our similar equipment can provide a single machine with a calorific value of 18 million kcal, and more than 90% of the manufacturers in the same industry can only achieve equipment with a calorific value of less than 3.6 million kcal; our equipment can not only achieve full automation, but also realize cloud control. , a mobile app can operate and monitor equipment operation.


  • Is your equipment environmentally friendly and can it pass the inspection of relevant departments?

Our equipment has passed the inspection of the Provincial Quality Supervision Bureau and has relevant test reports; our company has the national ISO quality management system certification, and the design and production of all products conform to the relevant national standards of the industry; our newly designed catalytic low-nitrogen combustion The technology can meet the national emission standard without denitrification of the exhaust gas; our company has complete exhaust gas treatment equipment, and you are also welcome to taste and purchase.
