DSH Burners
The company has come up with a new system (Burners) for Industries, which are
already using direct Biomass (sawdust, ricehusk, wood) or Coal in their boilers or furnaces.
This Burner can be attached at the mouth of the boiler/furnace.
The fuel can be sawdust, ricehusk, coal, wood, any other biomass, etc.
The fuel will go into this burner, Semi Gasification will happen and the gas generated can be used in boilers/furnaces.
Advantages
Advantages
1. No Emission of smoke from the boiler/furnace chimney. No Air Pollution.
2. Savings of 30-40% against direct Biomass or Coal use.

Types of Burners
- SawDust/Rice Husk Burner
- Coal/Wood Powder Burner
- Biomass Wood Chip Burner
- Biomass Pellet Burner
- Industrial Sludge Burner
Saw Dust / Rice Husk Burner
The raw materials are fed into fuel bin and through air fan are blown into the sawdust / rice husk burner.
Through high-temperature cracking and suspended semi gasification combustion, the heat generated is
transferred to the energy-using equipment. The principle of radiant and convection heat, three- stage of
air distribution and increase in oxygen supply, resultin sawdust/ rice husk burning fully in the furnace and
more than 95% of heat s transferred to energy-using equipment.

Industrial Sludge Burner
Using a sludge-coupled biomass pyrolysis gasification treatment process, the Industrial Sludge Burner is
designed and developed according to the purpose and principle of sludge disposal reduction, resource
utilization and stabilization. This technology is also a kind of combustion technology, but unlike
incineration, it uses the principle of anaerobic combustion, also known as pyrolysis gasification. It not only
solves the problem of large investment in sludge incineration, large exhaust gas emissions and high toxic
and harmful gas content, but also helps in disposal of domestic garden and agricultural waste and at the
same time reducing cost of treatment considerably.
Advantages of Sludge Burners
Advantages of Sludge Burners
1. The technology inherits the advantages of incineration, which can minimize the volume of sludge (sludge with 80% moisture reduction of 92% or more) and there is no heavy metal and pathogenic bacteria-borne diseases. It is more effective than incineration, which required high investment and operational cost and had a difficult emission treatment process. It also solves the problem of difficult
processing of agricultural and forestry waste in some areas.
2. The technology utilizes the heat of sludge itself, and combines a small amount of cheap biomass fuel to dry the sludge as a heat source, which greatly reduces the cost of sludge drying. The most costly part of sludge treatment is the dehydration stage. Through the treatment of pyrolysis gasification technology, the total exhaust gas generated by the process is 20% of direct incineration, and the harmful gas content is less than 10% of incineration. This not only reduces the cost of gas treatment greatly but also meets environmental emission standards.
3. The pyrolysis and gasification system is based on the characteristics of garbage, and realizes a two stage treatment process for the first pyrolysis and gasification of the garbage and subsequent oxygen enriched combustion, so that the garbage is completely burnt. After the treatment, the residue burning rate and leaching toxicity is lower than national standard.
4. Since the pyrolysis gasification chamber (secondary chamber) burns gas and the excess air coefficient is small, the amount of flue gas generated by the pyrolysis method is lower than that of the direct incineration method, especially the content of pollutants such as SOx, NOx, HCL, HF and heavy metal. Itis conducive in the purification of flue gas, reducing the secondary pollution emissions and treatment costs.
5. The pyrolysis gasification process is conducted under low oxygen and no oxygen conditions, which reduces the generation of dioxin precursors. The temperature in the second combustion chamber is upto 1100° C, and residence time of flue gas is more than 2 s, and the dioxins can be rapidly decomposed, thereby reducing the content of harmful substances such as heavy metals and dioxins in the fly ash discharged after garbage disposal, thereby reducing secondary pollution to the environment
