SZL10-1.25-T boiler is a double drum longitudinal arrangement type water tube chain boiler. This series of biomass fired boiler fuel from the front coal hopper into the front end of the grate, after combustion into the slag extractor discharged. Biomass fired boilers manufacturer advanced production technology, absorb advanced production experience, product quality is guaranteed. The boiler has two sets of convection tube bundles ⅰ and ⅱ arranged between upper and lower drum, tube size φ51×3, the material is no. 20 boiler seamless steel tube, the tube bundles are arranged in line, transverse pitch S1=120mm, longitudinal pitch S2=85mm, transverse 18 rows each, longitudinal 21, 14 rows respectively.
SZL biomass boiler grate on both sides into the air, air chamber equipped with air baffle, can accurately adjust the fuel at each stage of combustion air volume, so that the fire bed with uniform air, for the combustion of coal. According to the characteristics of biomass fuel combustion, this type of steam boiler adopts shorter furnace arch and secondary air, as well as larger furnace volume, which can make the fuel burn fully and effectively in the furnace. The boiler is divided into two parts factory, easy to install and move, assembly boiler factory to the scene, only need to combine the two parts, build the upper and lower furnace wall, install the slag machine, fan and other auxiliary systems and smoke duct, and connect water and electricity can run, easy to install, short cycle.
Biomass fired boilers manufacturer produce boilers that are compact and have a small footprint. Boiler only need single layer arrangement, so civil engineering investment is low. SZL series steam boiler water wall tube arrangement is close, effectively reduce the temperature of the furnace wall on both sides, so both sides of the water wall after the furnace wall can be used light furnace wall, effectively reduce the weight of transport, and has the characteristics of starting, fire fast. The boiler can run stably under 70%-100% working condition. The boiler operation parameters under 100% rated load are as follows: feed water temperature is 20℃, rated pressure of boiler is 1.25mpa, 10 tons of steam produced at 193℃, calculated thermal efficiency is 81.22%, and exhaust temperature is 155℃. The calculated fuel consumption is 2267.4Kg/h biomass pellet fuel (the fuel indicators should comply with the relevant provisions of the manual).
This series boiler is equipped with water supply flow meter, steam flow meter to indicate the boiler to give water and steam production, and equipped with oxygen meter to exhaust smoke detection, the boiler fuel metering through the boiler coal volume integrator to realize the amount of indication, integrator and record. Equipped with safety accessories can effectively monitor and control water level and pressure, with low water level automatic water, high water level automatic stop pump work, the boiler has high water level alarm, low water level alarm, low water level interlock protection, overpressure alarm and overpressure interlock protection functions. At the same time, different sound and light signals can be sent out to remind the stoker to adjust the operating condition of the equipment in time and effectively prevent the occurrence of accidents.
Biomass fired boilers manufacturer produce boilers with low operating costs, mainly due to cheaper fuel and scientific structural design. The steam boiler has a scientific structure and reasonable design. The furnace of the boiler has a large heating area, which can make the fuel fully burned in the furnace and make the heat fully converted. SZL series boiler grate side sealing structure design advanced and reasonable, to avoid the side sealing card grate and grate on both sides of the air distribution is not uniform and burned side sealing defects. Single return thread pipe is used in the barrel to enhance the heat transfer effect, and the thread pipe has the function of self-cleaning ash, to avoid ash accumulation in the pipe.
