15 Ton Coal Fired Boiler Price

SZL 15 ton coal fired boiler is a double-barrel longitudinal chain grate assembly water tube boiler, which is mainly composed of upper and lower barrel, convection tube bundle, water-cooled wall tube, descending tube and collection box, upper and lower barrel longitudinal arrangement, combustion equipment using chain belt type chain grate, driven by stepless variable speed device.

SZL 15 tons assembly chain grate boiler main technical parameters

1. Rated evaporation capacity: 15 tons / hour
2. Rated working pressure: 1.25MPa/1.6MPa
3. Design fuel: coal (poor coal, lignite, coal, bituminous coal, anthracite) and biomass (straw, rice husk, wood, wood chips, bagasse, palm husk, etc.)
4. Rated steam temperature: 194℃/204℃
5. Boiler thermal efficiency: 80%
6. Maximum transport size: 9300*3310*3530

SZL 15ton assembly chain grate boiler is widely used in the textile, printing and dyeing, paper, chemical, food and other industries to provide the required steam heat for their product processing process.

SZL 15 tons assembly chain grate boiler advantages

1. The furnace chamber and combustion chamber on both sides of the membrane water-cooled wall structure. Membrane water-cooled wall structure is our company’s independent design original design, the membrane water-cooled wall structure used in power station boilers applied to the assembly boiler, the advantages of its heat transfer coefficient is large, good conduction effect, low heat loss, good airtightness, furnace wall does not deformation, no ash leakage.
2. Front and rear water-cooled wall tubes of the furnace chamber extend downward to the upper part of the grate to form the front and rear arches. The structure is added on the basis of the original mature bulk boiler, on the basis of other heating areas remain unchanged and increase the radiating heating surface of the furnace, the overload capacity is stronger; before and after the arch a water-cooled wall tube for the skeleton and high alumina cement pouring, thus avoiding the original boiler three fold line arch brick long-term high temperature grill fracture, arch collapse of the malady, thus extending the service life of the arch.
3. The arch design adopts the inverted “α” arch technology of “Xi’an Jiaotong University National Science and Technology Progress Second Prize”, the front arch is high and short, the rear arch is low and long, which increases the combustion time of the flue gas in the furnace chamber and improves the combustion efficiency; the streamlined rear arch can throw the unburned carbon particles blown up from the rear of the grate to the front, which makes the coal easier to ignite and the ignition line is neat; the coal type is widely applicable.
4. The length of the front and rear shaft of the furnace is longer than that of the same type of domestic products, which prolongs the burning time of the fuel in the furnace chamber, makes the coal burn fully and reduces the carbon content of the slag; increases the effective area of the grate, and the overload capacity of the boiler is obviously enhanced.
5. Using double side air inlet, six independent air chambers are set up along the longitudinal direction of the grate, and there are independent air regulating devices between each chamber to adjust the air volume size of each chamber respectively to achieve the best adjustment and combustion effect.
