DZL horizontal biomass hot water boiler is a kind of horizontal three return water and fire tube mixed boiler, arranged in the drum of a bunch of threaded smoke pipe. The left and right sides of the furnace are equipped with light tube water-cooled walls. Horizontal hot water boilers adopts light chain grate to realize mechanical feeding, equipped with blower, induced draft fan for mechanical ventilation, and equipped with scraper type slag machine to realize automatic slag.
The front and rear arches of biomass fired hot water boilers adopt new energy-saving furnace arches. Fuel from the hopper fell on the grate, into the furnace after burning, the flame through the rear arch refraction upward through the body on both sides of the burning chamber fold to the front smoke box, and then from the front smoke box back to the pot tube bundle, through the smoke box into the economizer, and then by the induced draft fan pumping through the flue to the chimney exhaust to the atmosphere.
Horizontal hot water boilers type of horizontal quick loading boiler, natural circulation of working medium. The boiler heat exchange system is composed of drum, left and right collecting boxes and water wall. The main heating surface is water wall of furnace chamber, part of drum and convection tube bundle in drum. The boiler design performance is advanced, the main heating surface pipe is made of 20# low and medium pressure boiler with seamless steel tube, drum is made of boiler special steel plate. The left and right collection boxes are made of seamless steel tubes.
This series of biomass fired boiler furnace arch is made of refractory concrete. The rear arch is low and long, so it burns well, and the flue flue and side wall tiles are made of refractory sintered bricks. The boiler front wall and back wall are made of general firebrick. The grate air distribution is reasonable, the combustion chamber is large, and the coal type is applicable strongly. Adapt with biomass pellets and all kinds of bituminous coal or anthracite, mixed coal. Full combustion. Because the high temperature flue gas first enters the settlement chamber, and then enters the two flue flue and the front smoke box from both sides, the smoke and dust removal effect is good.
The water circulation of the boiler is simple, the structure of the pressure parts is reasonable, and under the condition of ensuring the water quality, it can be safely operated. This series of boiler products adopt the popularized green renewable biomass wood pellet fuel, the CO2 emission is zero, the smoke emission concentration is less than 50mg/m3, the smoke black is less than Ringmann I level, and all the indicators meet the first-class regional environmental protection standards.
The fuel wood biomass pellet used in this series of hot water boilers is a new type of environmental protection fuel, which is a renewable resource. This boiler product has the characteristics of high calorific value, low cost and wide range of sources. Horizontal hot water boilers has high degree of automation and low operating cost. Using digital integrated controller, can be set according to the user automatic controller combustion conditions, simple and convenient operation, automatic ignition, automatic feeding, automatic dust removal, gas boiler operation is equally convenient.
