The DZL series biomass steam boiler independently developed by Fangkuai is a new fourth-generation horizontal water-fire tube quick-installed chain grate boiler. This series of boilers has the advantages of fast installation, time-saving and material-saving, compact structure, small footprint, high reliability, high thermal efficiency, and strong overload capacity, etc. The large parts of the boiler (upper body and lower base) have been installed in the factory After the assembly is completed after the large parts of the boiler are put in place at the user’s site, it only needs to complete the various interfaces, auxiliary machines, and piping systems to operate. DZL series boilers adopt light chain grates, a high degree of automation, are equipped with high-efficiency dust removal equipment, have less environmental pollution, have good comprehensive economic and technical indicators, and are well received by consumers.
Digital integrated controller, which can set the combustion conditions of the automatic controller according to the user. The operation is simple and convenient, with automatic ignition, automatic feeding, and automatic ash cleaning.
The main heating surface tubes of the biomass fired steam boiler are made of seamless steel pipes suitable for low and medium-pressure boilers, the drum is made of special steel plates for boilers, and the left and right headers are made of seamless steel pipes.
Since the high-temperature flue gas enters the settling chamber first, and then enters the two-wing flue and the front smoke box from both sides, the smoke and dust removal effect is good.
Industrial biomass steam boiler adopts a chain-belt or small-scale grate and assembly structure, with a compact structure, and the boiler room can be arranged in a single layer.
The primary components of a biomass steam boiler combustion system include the fuel delivery system, the combustion chamber, the air supply system, and the ash handling system. The fuel delivery system is responsible for feeding the biomass fuel into the combustion chamber at a controlled rate. The combustion chamber is where the biomass fuel is burned to generate heat. The chamber may be designed to facilitate the complete combustion of the fuel, which can help to maximize energy efficiency and reduce emissions. The air supply system provides the oxygen necessary for the combustion process to occur. Finally, the ash handling system is responsible for collecting and removing the ash generated during the combustion process.
The emission control system of a biomass-fired steam boiler is designed to minimize the release of pollutants into the atmosphere during the combustion process. Particulate matter (PM) control equipment includes cyclone separators, electrostatic precipitators (ESPs), or fabric filters (baghouses) to capture particulate matter generated during combustion. Nitrogen oxide (NOx) can be reduced using several methods, including selective non-catalytic reduction (SNCR), selective catalytic reduction (SCR), or low-NOx burners. Carbon monoxide (CO) can be minimized by optimizing combustion conditions and ensuring complete combustion of biomass fuel.
