Product Details

With the increasing demand for energy in society, fossil fuels, as the main source of energy, are rapidly decreasing. The demand for renewable energy is increasing day by day. Renewable energy refers to non fossil energy sources such as wind, solar, hydro, biomass, geothermal, and ocean energy. Biomass is an ideal renewable energy source with a wide range of sources, producing a large amount of industrial, agricultural, and forest waste every year. As renewable resources such as corn cobs and straw in northern China, as well as rice husks, bagasse, and coconut shells in southern China, are abundant, using them to replace or partially replace coal can bring substantial economic returns to enterprises. On the other hand, biomass energy is a clean and renewable energy source with nearly zero carbon dioxide emissions. Therefore, utilizing biomass energy plays an important role in protecting the environment, improving ecology, and enhancing the living standards of farmers.

The calorific value of every 3 tons of straw is equivalent to 2 tons of coal. According to incomplete statistics, the annual crop straw production in China is about 650 million tons, and it is expected to reach 956 million tons by 2015.

◆ Product Usage:

Burning biomass fuels can also be used as pure coal or mixed fuels such as straw (distiller's grains, sawdust, peanut shells, etc.) to provide thermal energy or generate electricity.

performance advantage

1. In terms of structural design, the straw boiler of Henan Yongxing Boiler has a relatively large furnace space compared to traditional boilers, and the layout of secondary air is very reasonable, which is conducive to the full combustion of biomass fuel during combustion.

2. The Zhengguo straw boiler adopts a double drum horizontal structure, which completely overcomes the phenomenon of overheating and bulging caused by the drum being directly exposed to the furnace, and the arrangement of the heating surface is more reasonable. The membrane water-cooled wall structure is adopted on both sides of the furnace, which ensures the sealing of the furnace and improves the thermal efficiency of the boiler.

3. The convection tube bundle of the boiler and the heating surface of the economizer are reserved with soot blower interfaces, and necessary measures can be taken to prevent accidents for special fuels (especially those with strong adhesion).

4. Adopting improved GEF specific slag removal technology; The grate adopts a new type of small scale grate plate and adds a unique safety ring, which completely solves the technical problem of grate plate detachment, effectively reduces grate air leakage, makes grate operation stable and reliable, and greatly improves combustion efficiency.

5. High degree of automation, digital integrated controller, can automatically control combustion conditions according to user settings, simple and convenient operation, automatic ignition, automatic feeding, automatic ash cleaning, and equally convenient operation as fuel and gas boilers. Adopting inverted“ α ” The furnace arch technology improves fuel combustion characteristics and has a wide adaptability to coal types.

6. The furnace arch adopts a water-cooled arch structure, which not only increases the rigidity and stability of the furnace arch, but also extends its service life.

7. By adopting a unique secondary air structure, the air force field inside the furnace is effectively improved, directing hot particles towards the front arch, which is beneficial for fuel ignition and prolonging the residence time of the fuel in the furnace, thus improving the adaptability and utilization rate of the fuel.

8. Low operating costs: Due to the nature of the fuel used by the boiler itself, biomass particles are a new type of environmentally friendly fuel supported and promoted by the state, and are a renewable resource. It has the characteristics of high calorific value, low cost, and wide source. Its operating cost is only a quarter of that of electric boilers and less than half of that of oil (gas) boilers.

9. Safety: High standard and high-quality auxiliary equipment, accessories, and automatic control devices are used to ensure the safe and stable operation of the boiler.

working principle

Water cooled walls are arranged on both sides of the straw boiler to form the furnace and convection flue. A single return threaded smoke pipe is arranged inside the drum, providing greater combustion space and sufficient height to allow sufficient combustion time for the fuel in the furnace. There is a cast iron economizer at the tail. The furnace adopts water-cooled integral pouring front and rear arches. The front arch is in a stepped shape, and the rear arch is in a herringbone shape, which makes the coverage rate of the arch close to 85%, which is conducive to the combustion of bituminous coal. Adopting a large block chain grate to achieve mechanical combustion. Equipped with a drum induced draft fan for mechanical ventilation, sufficient secondary air is arranged in layers at a certain height in the furnace, and a slag removal machine is used to achieve mechanical slag removal. The control and monitoring instruments are complete.
