DZL series coal fired boilers are horizontal three – pass water & fire tube boilers with a chain grate stoker structure, burning medium bituminous coal. The DZL series coal fired boilers body is arranged in the longitudinal direction of a single boiler barrel, the threaded firework pipe inside the boiler barrel constitutes the convection heating surface, the boiler barrel and the water cooling walls on both sides constitute the furnace radiation heating surface, and the combustion equipment adopts the light chain grate. The whole fast installation form leaves the factory. Electric control realizes stepless speed regulation, limit parameter alarm and interlocking protection.
Coal fired boilers have compact structure, small floor space, short installation cycle, low installation cost and low capital investment. The heating surface layout of this DZL series coal boiler is reasonable and sufficient, the boiler temperature rises, the pressure rises quickly, the output is sufficient, the thermal efficiency is high. The grate is divided into air bins, the air volume of each bin is independently adjustable, and the grate is stepless speed regulating, which adapt to the wide variety of coal and the fuel combustion is more sufficient.
DZL type coal fired boiler is a horizontal three-return water and fire tube boiler. The design adopts high efficiency and energy saving enhanced combustion technology to ensure the full combustion of fuel. Even better, the volume of the furnace and the combustion chamber is very large, which is conducive to the combustion and settlement of fly ash. The dust separation and diversion chamber at the exit smoke window achieves the purpose of dust removal in the boiler, reduces the emission of smoke, and makes it meet the target stipulated by the state environmental protection.
The application of membrane water wall structure in coal-fired boilers improves the heat transfer coefficient and the heat transfer effect and reduces the heat loss. The welding seam of boiler adopts advanced submerged arc automatic welding technology, which ensures the welding quality. High automation level, with automatic water regulation, low water level interlock protection, high and low water level alarm and other functions. The control monitoring instrument is complete, the boiler operation is safe and reliable.
