Chain grate coal-fired boilers have high efficiency, strong overload capacity and wide adaptability to coal species. Coal fired boiler manufacturer produce SZL series hot water boilers, which can be used for bituminous coal, anthracite, lignite, etc. The series boiler is mainly composed of upper and lower drum, convection tube bundle, water wall pipe, down pipe and collector box. The upper and lower barrels of the boiler are arranged longitudinally. The combustion equipment adopts a chain grate and is driven by a stepless variable speed device.

The coal-fired hot water boiler is equipped with water-cooled walls around the combustion chamber, and the front and rear arches are made by pouring refractory castables with the water-cooled walls as the skeleton, and the furnace arch has a longer service life. The left and right sides of the body are full-membrane water wall structure, the boiler has good sealing performance, low heat dissipation loss, and guarantees the safe and efficient operation of the boiler. This series of hot water boilers adopts advanced threaded smoke tube structure with high heat transfer coefficient and low heat dissipation loss. At the same time, the use of advanced control systems and reasonable model selection will save you investment costs while ensuring stable operation.

Coal fired boiler manufacturer have rich production experience, boiler combustion efficiency is high, output is sufficient. Coal-fired hot water boiler refers to the boiler with coal fuel, mainly used for heating hot water. The coal-fired hot water boiler comprises a furnace shell, a furnace, a firework channel and a water interlayer. The furnace is located in the lower part of the furnace shell, the lower end of the firework channel is connected with the upper end of the furnace, and the water sandwich is located in the inner side of the furnace shell and between the furnace shell and the firework channel. In the upper and lower parts of the furnace shell are respectively a water outlet and a water outlet, in the middle of the corresponding furnace shell side of the furnace mouth, in the top of the furnace shell is a smoke outlet, the fireworks channel has a plurality of and vertical interval layout, between each fireworks channel for water interlayer, the inside of the water interlayer are compound a layer of pond porcelain layer.

The series hot water boiler is designed according to atmospheric pressure, the top of the furnace body is provided with an air opening, the boiler runs without pressure, and the combustion operation is safe and reliable. Atmospheric pressure hot water boiler can be installed in any place where it is used, and is not restricted by various annual supervision procedures, so it has developed rapidly in recent years. The boiler body has compact layout, small occupation area, convenient transportation, quick installation, short installation cycle, low installation cost, less user investment and quick recovery benefit. Coal-fired hot water boilers are widely used in factories, hotels, hospitals, office buildings, schools, bathing centers, baths and other enterprises and institutions to meet the requirements of bathing, domestic hot water and heating.

Coal fired boiler manufacturer adopt advanced technology and high degree of automation, and can accept customized boiler services. Coal-fired boiler grate is reliable in quality. The new generation of products with higher grade, the use of large core grate. Material use heat resistant malleable cast iron, greatly improve the tensile strength and heat resistance, and easy maintenance. Grate frame from the original steel plate “T” type lap to light rail, effectively prevent high intensity combustion caused by thermal deformation. The improvement of grate quality reduces the failure rate of operation and ensures the stable gas supply and heating requirements of users.
