DZL type chain grate boiler is a horizontal three-pass fire tube boiler mixed, arranged in a bouquet of threaded pipe drum. The left and right sides of the furnace tube equipped with a light water-cooled wall. Using light chain grate stoker achieve with blower, Fan mechanical ventilation, and air-scraper slag machine automatic slag. The furnace arch around the use of new energy-saving technologies furnace arch. Fuel from coal bucket fell on the grate into the combustion chamber, the flame is refracted through the arch upward through the body off to the side room to burn out before the smoke box, and then turn back from the pot before the smoke box control, and after the adoption of the smoke box into the economizer, then evacuating the draft fan to the chimney through the flue to the atmosphere. Features: 1. Horizontal Packaged Boiler type of fire tube boilers, natural cycle working fluid. The boiler heat exchange system by the drum, left header, water wall, which mainly have the furnace water wall heating surface, convection tube inside the drum and the drum section. When the product manufactured by the five major components: the main boiler, smoke duct, precipitators, piping systems. Of which the first four parts have been manufactured in the factory is completed, transportation to the installation site can be assembled, can greatly shorten the installation cycle, and can be installed to ensure product quality. 2. Advanced Design Features: The main boiler heating surface in a 20 # low pressure boiler seamless steel tubes made of boiler drum using special steel. About collection box is made of seamless steel pipe. 3. The use of refractory concrete arch furnace boiler pound crafted. After the arch is low and long, and therefore good combustion, flue wings and side wall using sintered refractory bricks. Boiler front wall, back wall using a common firebrick. 4. Grate with the wind and reasonable, the larger chamber, coal applicability. Adapt to all types of bituminous coal or anthracite coal mixed. Combustion. Due to the high temperature flue gas first enters the settling chamber, and then from both sides of the flue into the wings, before the smoke box, so good smoke and dust effects. 5. The water cycle is simple, reasonable structure and pressure parts, to ensure the quality of the situation, can operate safely. 6. combustion equipment for quick grate combustion equipment installed in the factory, manufacturing, transportation mounted directly on the ground you can post to the site. With a reasonable structure, compact, low consumption of steel, the boiler performance, weight, size and structure of the domestic product, compared with the capacity it has obvious advantages. Boiler work process: a substantially uniform particles by automatic stoker coal investment falls within the coal bucket, arch preheating zone before entering in the rotation of the chain grate. After falling into the slag pool fire burn area. High temperature flue gas generated by the combustion chamber by arch opening into the furnace flue at the lower rear of the wings, and then by the two wings of the flue heat, smoke box before flowing forward, enter into the convection heat transfer tubes Sheng Mei from the rear drum , dust collector, induced draft fan fed through the chimney into the atmosphere. Boiler feed water from the boiler feed pump is completed, demineralized water supply from the economizer, and then enter the drum, and then by the drop tube into the left header. Both sides of the Wall endothermic vaporization produces steam, steam into the drum separator, separated into the required heat flow from the main steam valve.
