DZL Series Coal Fired Industrial Hot Water Boilers
Capacity: 1.4 – 7 MW
Pressure: 0.7 – 1.25 Mpa
Temperature: 115 / 70, 95 / 70 ℃
Fuel: Bituminous Coal,Lean Coal,Anthracite
Industries: Heating, Hotels, Schools, Hospitals
The DZL series quick-installed boiler is a horizontal three-pass water-fire tube chain grate boiler designed for bituminous coal combustion. The boiler features a single drum layout with threaded smoke tubes for convective heating surface, and water-cooled walls on both sides of the drum for radiant heating surface. The combustion equipment adopts a lightweight chain grate, and the boiler is delivered in a complete quick-installed form. The electrical control system enables infinitely variable control of the grate, with alarm and interlock protection for critical parameters.
Easy Maintenance
Horizontal coal-fired atmospheric pressure hot water boiler, the upper is equipped with enough manhole, personnel can enter the furnace body from the manhole, greatly facilitate the inspection and maintenance of the boiler.
Wide Applicability
DZL coal-fired industrial hot water boiler is widely used in factories, hotels, hospitals, office buildings, schools, bath centers, baths and other enterprises and institutions, to meet the use of the unit bath, domestic hot water and heating requirements.
Environmental Protection and Energy Saving
Horizontal coal-fired hot water boiler belongs to the vertical type of single boiler barrel in structure. Water wall pipes are installed on the left and right sides of the furnace, and wing flue is formed. Threaded smoke pipes are arranged in the boiler barrel.
After the fuel in the combustion, the flame through the low wall to the combustion chamber, the state from the combustion chamber state through two flanks form before flue to smoke box, again by smoke tube bundle to the smoke chamber, then northwards by induced draft fan through the chimney discharged into the atmosphere, not only can prevent the at the bottom of the pot shell from furnace heat radiation, and can make high temperature smoke tube plate inlet temperature drops, and supplemented by water ejector, no dead zone at the bottom of the drum, also can effectively prevent the tube plate because too cold, boiling and scaling and furnace bottom convex hull, smoke to the smoke chamber can dust removal effect, also reduces the original exhaust dust concentration.
Low Cost
Horizontal coal-fired atmospheric pressure hot water boiler, the use of a single boiler tube longitudinal layout of the three-return fire-water tube structure, both sides of the furnace covered with light tube water-cooling wall tube, the design structure is reasonable and compact;The heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical.
The boiler body is compact in layout, occupies a small area, convenient in transportation, adopts quick delivery, short installation period, low installation cost, less user investment, quick recovery benefit.
