Coal fired boiler design structure has reasonable, large heat transfer area and good heat conduction effect. At the same time, the boiler product also has the advantages of small heat loss, good air tightness, no deformation of the furnace wall, no leakage of ash and so on. The boiler can burn second class bituminous coal, and can burn firewood (wood chaff), wood industry waste, good environmental protection benefits. Widely used in schools, textile mills, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, bean products factory, meat products factory, cannery, winery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.
Coal-fired boilers have adopted the latest scientific research achievements such as arch tube plate and threaded pipe pipe technology, which have solved the problems of cracking tube plate, bulging at the bottom of drum, low thermal efficiency, insufficient output and poor adaptability of coal blending. Scientific design, exquisite appearance using cabinet type scientific design style, internal design structure is reasonable, maintenance is extremely convenient. No drum, induced draft fan cost investment, save electricity, products are quick installation factory, easy to install. It can be used in the first class environmental protection area without disturbing the people with noise.
The boiler grate stepless speed regulation, can be suitable for different types of coal combustion requirements, combustion is sufficient. Coal fired boiler design are compact and small in footprint, boiler room single-layer layout, less capital investment, assembly height, short installation cycle. The boiler has reasonable overall design, simple structure and convenient operation and maintenance. The boiler adopts automatic control and monitoring instrument, high automation, safe and reliable, easy to operate.
DZL series coal-fired boilers are characterized by quick installation, material saving and man-hour saving. The boiler also has the advantages of high reliability, high safety, strong overload capacity and high thermal efficiency. The large parts of the boiler (mainly the upper body and the lower base) have been assembled in the plant. After the large parts of the user’s boiler (mainly the upper body and the lower base) are in place, it only needs to complete the interfaces, auxiliary machines and piping system to run.
This series of boiler products grate side sealing structure design is advanced and reasonable, both sides of the air inlet; Adopt the new curved arm screw air conditioning structure, so that the ventilation section ratio of the air conditioning reaches 100%; Flexible adjustment, uniform distribution of wind. Push-pull type sluice cleaning device is designed. The sluice is made of heat-resistant cast iron, which is finished and sealed to effectively prevent secondary combustion deformation and grate air leakage. By pulling part of the rising pipe on both sides of the collecting box to the furnace, and then introducing the lower part of the cylinder side and the heat insulation at the bottom of the cylinder to form the heating surface of the furnace top, the novel furnace structure successfully solves the problem that the bottom of the cylinder is directly radiated by the high temperature flame and avoids the defect of “bulge”.
The coal fired boiler design is novel and reasonable, the application scope is wide, the use of energy saving and environmental protection, the mechanization and automation degree is high. Water wall is arranged on both sides of the boiler to form a furnace and convection flue, a single return thread flue is arranged in the pot drum, and a cast iron economizer is arranged at the end. The front arch and back arch of water cooling are used in the furnace. The front arch is stepped and the rear arch is herringbone, making the arch coverage rate close to 85%, which is conducive to the burning of bituminous coal.
