8 t/h DZL automatic chain grate biomass/wood pellet fired steam boiler for sauna

1. Introduction:
- The DZL type biomass boiler produced by the company is a single-drum vertical biomass boiler. This type of boiler uses biomass pellets made from straw waste, sawdust, peanut shell and other crop waste as fuel. It uses a new furnace design to maximize fuel combustion and heat transfer through a built-in three-return thread pipe. The thermal efficiency of the boiler reached 82.6%.

- For factory, biomass not only reduce costs, but also reduce environmental pollution. Straw fuel is a kind of biofuel. It uses straw fuel pellet machine to make sawdust, corn stover, peanut shell, straw, cotton stalk, branch, edible fungus waste and cow dung into high-density flammable high-quality granules. . Biomass combustion boilers are treated as “waste” and “waste”, which has become a new direction for carbon zero emission and environmental protection.

- It is understood that biomass fuel boilers are designed for waste in various processing industries. The main fuels include waste wood, rice husks and corn cobs.

- Using waste as a suitable fuel, the burned ash can also be used as a farmyard fertilizer, and it is an energy-saving and environmentally friendly product.

- Biomass boilers use advanced automatic control technology, such as automatic water supply adjustment, program start and stop, fully automatic operation, etc., easy to operate, easy to use, with high and low water level alarm and high pressure alarm, flame out protection and other safety measures, comprehensive protection of the boiler safe to run.

2. Product technical features:
- The boiler completely realizes the purpose of low-temperature combustion, and adopts the medium-temperature separation technology to make the flue gas temperature of the whole circulating flow field of the boiler lower than the ash melting point temperature of the biomass fuel;
- A good material circulation loop is established inside the boiler, the fuel is fully mixed, the furnace temperature is uniform, the fuel combustion efficiency is high, the fly ash has a very low carbon content, and the air pollution is small;
- A variety of technologies are used in the boiler design process to effectively avoid boiler ash and coking, so that the boiler has strong continuous operation capability;
- In the boiler design process, the corrosion problem caused by biomass fuel such as straw is well solved, which greatly prolongs the service life of the equipment;
- The boiler has good fuel adaptability. It can not only achieve stable combustion for many types of soft and hard straw, but also achieve design parameters smoothly.
- The boiler has good dynamic response capability, convenient start-up and fast load-lifting speed; the boiler combustion device has no moving parts and the maintenance cost is low.
