*********
Forming solid biomass fuels (referred to as biomass fuels, commonly known as: Wood, straw, coal), is the use of new technologies and specialized equipment will crop straw, wood chips, sawdust, peanut shell, corn cob, rice straw, rice husk, straw bran, branch leaves, hay and other modern compression molded carbon clean fuel, biomass fuel sources extensively, is an inexhaustible renewable energy, biomass burn rate of 96%, 4% ash can be recycled and the remaining K to achieve a "straw - Fuel - fertilizer" in circulation.

*********
Use of biomass fuels, clean and environmentally friendly, renewable energy, environmental protection consistent with national energy policy received strong advocate and promote.

********
Biomass fuels as coal, oil, natural gas, the fourth largest energy, it will become the world's largest energy the most important. Biomass fuel containing sulfur is very low, the problem does not exist desulfurization, heat value in 3600 ~ 5100 kcal / kg, not only can replace the coal and other fuels, and its low price, the boiler operating costs greatly reduced, and fuel oil, gas, compared with electric boiler, the cost decreased by 60%, 40%, 70%.

I. Features of Coal Fired Steam Boilers:
1). This thread boiler smoke pipe, arch tube sheet, wing flue structure, is the first victory in national development and National patent in 1991, after nearly two decades of continuous improvement and perfection of its structure is more reasonable, environmentally friendly energy. Effects become more prominent.
2). For the application of different fuels, chain grate and reciprocating grate is divided into two series. With energy, strong radiation arch, can be applied to all types of bituminous coal combustion.
3). With high standards, high-quality auxiliary equipment, accessories, automated control to ensure the boiler is safe, stable.
4). Compact, 1-10T / H fast assembly, 15-35T / H large assembly, single-layer arrangement, one-time investment province.
5). Boiler capacity of 1-35T / H (0.7-29MW).
II. Advantages of our production and service
1), 100%safety, running stably, excellent water level and pressure control, fully automatic operation
2), Boiler running life > 20years.
3), Good after-sale service. It is free for you to get the damaged spares in warranty period(1 year) if there is any questions. Assure that we can supply you spares in boiler's all life.
4), We can arrange engineer to your company for installation and commissioning and training. If you need us at any time, we can send our technicians and prepare in a short time.
5), Special paint is used after assembly. Paint is particularly used in your climate area, which is anti-corrosion, anti-abrasion and color-fastness.
III. Factory assurance:
1). One year parts warranty
2). Spare parts available at ex-factory price
3). Different voltage available
4). 100% tested before delivery
5). WNS steam boiler capacity ranging from 500 -- 30000 Kg/h.
6). Skid-mounted complete system available 100-- 2000 kg/h.
7). Complete system fixed in container available 100-- 4000 kg/h.
8). Engineer on-site instruction of installation and commissioning available.
