Abstract
The present invention relates to a new-type energy-saving environment-protecting water-tube boiler. It comprises upper central header, furnace cavity tube bank and water wall tube bank, side upper and lower headers and convection bank, etc. The water wall tube bank and furnace cavity front and rear wall tube bank are connected with upper central header and lower header, and closed by building refractory material to form ultralarge volume furnace cavity, and in the interior of said boiler a large-space smoke-dust sedimentation chamber and a forced circualting water channel are formed, and its lower portion is equipped with grate base seat. Said boiler can reduce smoke-dust discharge concentration, and can obtain the good energy-saving effect.
Description
Technical field
The present invention relates to a kind of civil boiler hot water field of boilers.
Background technology
Popular in the market hot-water boiler has many kinds, but can be classified as two big classes, one class is a multitubular boiler, one class is a water-tube boiler, the common drawback of this two classes boiler is a harrow-like implement for pulverizing soil steel amount height, boiler smoke original discharge concentration height, flue gas resistance is big, the power consumption height, and the different shortcomings of this two classes boiler are that the tube-plate fracture and the booster phenomenon of multitubular boiler is many, the fault rate height, the complex process of water-tube boiler, production efficiency is low, the cost height, and the present invention has not only solved above shortcoming, and comprehensive benefit highly significant such as energy-conserving and environment-protective.
Summary of the invention
The present invention adopts center collection case and next part case to connect and compose burner hearth by the water-cooling wall tube bank, economizes steel more than 30% than drum boiler structure, and combustion space increases greatly, and resistance to pressure strengthens greatly, technology advanced person, and production efficiency can improve more than 30%.
Twice expansion space of the present invention, the expansion space that burner outlet back ultra-large volume burner hearth and flue gas enter afterbody, twice dilatation deceleration gravitational settling, especially the expansion space that has water seal of afterbody, greatly reduce the original discharge concentration of flue dust after dust is fallen in the water, the boiler that comparable existing market is popular reduces original discharge concentration 8-10 times of flue dust.
The present invention is convenient to design economic velocity very much, is convenient to very much remove dust stratification, but the boiler power saving 20%-40% more popular than existing market.
