Guide: With the adjustment of industrial structure in large and medium-sized cities, the transformation of old districts and the construction of industrial zones, the implementation of the coal ban policy in central urban areas, and the implementation of energy-saving and emission reduction policies such as regional central heating and cogeneration, the proportion of small and medium-sized coal-fired boilers Will drop significantly
With the adjustment of industrial structure in large and medium-sized cities, the transformation of old districts and the construction of industrial areas, the implementation of the coal ban policy in central urban areas, and the implementation of energy-saving and emission reduction policies such as regional central heating and cogeneration Will decline significantly, and is now moving towards the direction of large capacity, high parameters, high energy efficiency, and low emissions; coal-fired boilers will be based on layered furnaces, that is, chain grate boilers will be mainly used, and the direction will be large capacity and high parameters. Development cannot be replaced by any other coal-fired boiler; boilers using clean combustion technology such as large-capacity circulating fluidized bed boilers (35t/h) have advantages in burning low-quality coal, energy saving, and environmental protection, and will get faster The development of oil and gas boilers will be developed to condensing low-nitrogen boilers, and the boiler water temperature will be discharged.
A stable fluidized bed requires a certain pressure drop on the air distribution board. On the one hand, the airflow velocity distribution under the air distribution board is uniform, and on the other hand, it can suppress the particle distribution and air velocity caused by bubbles and bed fluctuations. Uneven distribution. The pressure drop of the air distribution board is proportional to the square of the opening rate of the wind cap on the air distribution board. The pressure drop of the air distribution board will cause head loss and power consumption of the fan. Therefore, the resistance of the air distribution board during the design of the air distribution board is taken as the minimum pressure drop of the air distribution board required to maintain a uniform and stable bed.

Boiler discharge temperature, calculation of gas consumption of gas boiler is inseparable from the low-level heating value of gas and boiler thermal efficiency value, because the quality of natural gas supply in different regions is different, the quality of gas-fired boilers is different, the amount of mixed air is different, and the low-level heat of gas is different. The value is also different. The gas consumption calculation of gas-fired boilers should clarify the thermal efficiency value of gas-fired boilers. If the boiler has a higher thermal efficiency value, its gas consumption will decrease, and vice versa.
SZL series steam boiler is a vertical double-drum chain boiler drain tube boiler designed by Sony Boiler learning advanced domestic and foreign technology and combining its own experience. The 6-35 ton SZL series boiler is composed of upper and lower parts, the lower base is the combustion equipment, and the upper part is the heating surface of the body. In order to ensure accurate air distribution, the base design of the Xinli boiler uses multiple independent air chambers, which do not cross each other, and meet the air distribution requirements of different combustion stages through the air adjustment door. At the same time, the boiler furnace is composed of water-cooled wall tubes, front and back arches and hearths. Several return convection tube bundles are arranged at the rear of the body to adequately absorb the heat released by combustion. The SZL series chain grate steam boiler system customized by Xinli Boiler has excellent performance, and its thermal efficiency is more than 5% higher than similar boiler systems on the market.
