It has chain grate as burning device, upper-in-and-upper-out style natural water circulation with ejection for hot water boiler of this series, the right and left side of furnace as radiant heating surface, two wings of furnace and threaded smoke tubes as convection heating surface and three-dimensional shield shell. Furnace is divided by Smoke baffle wall into combustion chamber (firebox) at front and reburning chamber at back.Structure introductionThe new DZL series coal fired boiler is a single-drum vertical water-fire tube shell boiler, and the combustion equipment is a chain grate. The water walls on the left and right sides of the furnace are radiant heating surfaces, the two wings of the furnace are convective heating surfaces, and the convection heating surfaces of threaded smoke pipes are arranged in the drum. Shield shell.This series of coal fired steam boilers use the latest scientific research results, such as: arched tube sheet, threaded smoke tube, etc., to solve the problems of shell-type boiler tube sheet cracks, bulging at the bottom of the drum, tube bursts on the water wall, low thermal efficiency, and insufficient output. |

Technical characteristics(1) The arched tube sheet and the threaded smoke tube are used to form the drum, so that the drum is changed from a quasi-steel body to a quasi-elastomeric structure, and the bracing parts in the tube plate area are eliminated, and the stress is reduced. The smoke pipe is changed from two-pass to single-pass, which solves the problem of tube sheet cracks.(2) Due to the arrangement of the rising pipe row at the bottom of the drum, the dead water area at the bottom of the drum is eliminated, so that the sludge is not easy to deposit, and the high temperature area of the drum can be well cooled, preventing the bulge in the lower part of the boiler shell.(3) The use of high-efficiency heat transfer threaded smoke pipes achieves enhanced heat transfer effects, achieves the characteristics of rapid boiler heating and pressure rise, and improves the thermal efficiency of the boiler.(4) The structure is compact, and compared with the same type of boiler, the overall size is small, which saves the investment in the infrastructure of the boiler house.(5) Stable operation, convenient adjustment and sufficient output. Has a certain overload capacity.(6) Threaded smoke tube is used to enhance heat transfer, which improves the heat transfer coefficient and thermal efficiency. Because the flue gas has a disturbing effect in the tube, it is not easy to accumulate dust in the smoke tube, which plays a role of self-cleaning.(7) In the furnace, a high-efficiency and energy-saving furnace arch made of integrally cast heat-resistant concrete is used to improve the coal ignition conditions, and an independent air chamber is used to achieve reasonable air distribution, so that an aerodynamic field conducive to combustion is formed in the furnace. Expand the adaptability of coal types.(9) The arch of the boiler and the outlet smoke window have a certain effect of dust removal. The original dust concentration of the boiler is controlled below the standard, which ensures that the smoke and dust emission of the boiler meets the national environmental protection regulations.(10) The secondary air is arranged at the throat of the furnace arch, which can effectively organize the volatile matter in the fuel to mix with the air, promote the full combustion of the volatile matter in the furnace, and improve the fuel burnout efficiency.

What are the differences between vertical type boiler and horizontal type boiler with the same capacity?1. Structure of vertical boiler is compact, occupy a limited area,2. Convenient on installation and removal.3. Low cost and investment on capital construction. Steam exhausted fast and sufficient.1. The combustion space of horizontal is big, fuel can be burned completed.2. The thermal efficiency is higher than the vertical boiler,3. Horizontal type: less thermal loss, stronger output, and higher steam quality.2. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?Size requirement of coal:6-25mmSize requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%3. What is the size of furnace door and blower hopper?Size of furnace door:Standard elliptical furnace door:300*800*1500Blower hopper size:2 tons conical hopper: 1400*800*15004 tons conical hopper: 2200*1400*15004. What is the combustion mode of coal/biomass fired boiler?The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
