22 Ton Coal-fired Steam Boilers Price in Indonesia

Coal-fired boilers are widely used and have low cost. At present, coal-fired steam boilers are still widely used in some foreign countries where environmental protection requirements are not high, and play an important role in industrial production. ZOZEN’s 20-ton coal-fired steam boiler is SZL type chain grate coal-fired boiler with high efficiency, strong overload capacity and wide adaptability of coal types. It is praised as the design scheme of contemporary domestic similar products and has the world’s advanced level. The boiler is mainly composed of upper and lower boiler tube, convection tube bundle, water wall tube, drop tube and set box. The upper and lower boiler tube is arranged longitudinally. The combustion equipment adopts chain belt type chain grate and drives by stepless variable speed device.

Advantage of 20 Ton Coal-fired Steam Boiler

1. Membrane water-cooled wall structure is adopted on both sides of furnace chamber and burnout chamber. The membrane water-wall structure is designed by our company. The membrane water-wall structure used for power station boilers is applied to assembly boilers. Its advantages include large heat transfer coefficient, good conduction effect, low heat loss, good air tightness, no deformation of furnace wall and no ash leakage.
2. The front and rear water-cooling wall pipes of the furnace extend downward to the upper part of the furnace grate to form the front and rear arches. The structure is based on the original mature bulk boiler, and the radiation heating surface of the furnace is added on the basis of other unchanged heating area, which has stronger overload capacity. The front and rear arches are made of water-cooled wall pipes and poured with high aluminum cement, so as to avoid the defects of the original boiler three-line arch bricks, such as fracture and arch collapse due to long-term high temperature barbecue, and thus the service life of the arch is improved.
3. The furnace arch design special furnace arch technology, the front arch is high and short, the rear arch is low and long, smoke in the furnace combustion time, efficiency; The streamlined rear arch can throw the unburned carbon particles from the middle and back of the grate into the front part, making the coal easier to ignite and the ignition line neat. The applicability of coal is wide.
4. The length of the front and rear shaft of the furnace is longer than that of domestic products of the same type, so that the fuel is in the furnace for a long time, so that the coal is sufficient and the carbon content of the slag is reduced; The effective area of the grate is increased and the overload capacity of the boiler is obviously enhanced.
5. Adopt the air inlet on both sides, and set up six air Chambers along the longitudinal direction of the grate. The air regulating device in each air chamber can adjust the air volume of each air chamber respectively to achieve the regulating effect.

Coal consumption of a 1 ton coal-fired steam boilers: heat required by the boiler/calorific value of coal/thermal efficiency of the boiler; generally, the heat required by a 1 ton coal-fired boiler is 600000 CAL/hour. The calorific value of second-class bituminous coal is about 5500kcal/kg, and the boiler thermal efficiency is generally about 75%. Then, the coal consumption per hour of a 1-ton coal-fired hot water boiler is: 600000kcal/h÷5500kcal/kg÷75%=145.5kg/h. Then the coal consumption per hour of a 20-ton coal-fired hot water boiler is 145.5*20=2910kg/h.
