Product Name: Szl Series Assembled Coal Fired Hot Water Boiler (SZL) Model NO.: SZL4.2/5.6/7/10.5/14 Usage: Industrial Burning Style: Chamber Combustion Boiler Manufacturing Level: A Pressure: Low Pressure Drum Placement: Horizontal Boiler Water Circulation: Natural Circulation Media: Hot Water Structure: Water Tube Installation: Assembled Boiler Fuel: Coal-Fired Function: Hot Water Boiler Capacity: 1,2,4,6,10,15 T/H Optional Pressure: 0.7/1.0 MPa Optional Temperature: According to Requirement Certification: SGS,CE,ASME Control System: PLC Optional Transport Package: Exported Standard/According to Requirement; FCL Specification: SGS, CE, ASME Origin: China Mainland HS Code: 84021900 Product Description Product features1. The boiler adopts double drum, monolayer arrangement, compact structure, as well as large heating surfaces which are 10% more than those of same kinds of products, featuring the following advantages such as sufficient output, safe and reliable operation, short construction period, and low installation cost ect.2. The design of cyclone reburning chamber in furnace decreases dust contained in the flue gas. At the same time, incandescent carbon black particles burns further, enhancing the boiler thermal efficiency, and decreasing gas blackness, as a result, the gas emission concentration meets the requirements of grade A environmental protection area.3. The grate employs the technology patent of small roller structure, boundary grate and so on, improving the operation reliability of the boiler.4. Since the adoption of technology patent for the sealed wind chamber and bilateral grate air register, and the application of machining cone seal structure to grate adjusting air eauipment, the sensitivity of the grate is duely improved.5. Other energy saving equipments are optional according to the customers' requirements.Item/boiler type SZL4.2-1.0/95/70-AIISZL5.6-1.0/95/70-AIISZL7.0-1.0/115/70-AIISZL10.5-1.25/150/90-AIISZL5.6-0.7/95-70-AII(Q)SZL14-1.0/115/70-AIISZL7(10)-1.0/115/70-1.25-AIIdual for steam & hot waterRated thermal power (MW)4.25.6710.55.6147MW(10t/h)Rated effluent pressure (Mpa)1111.250.711.0(1.25)Rated effluent water temperature ºC95(60)9511515095115115(194)Rated return water temperature ºC70(45)707090707070Combustion modeChain grateChain grateChain grateChain grateChain grateChain grateChain grateApplicable coalAII AIIIAII AIIIAII AIIIAII AIIIAII AIII gasAII AIIIAII AIIIOpen grate area (m2)7.238.611.7216.49.921.3311.99Heated surface of boiler Proper (m2)157.6240.2243.2324240.2440232.3Heated area of boiler tail (m2)//174.4236/23352.7The coal consumption at full load operation (Kg/h)896.6(943)1186.61507.62258118629381407(1507.3)Thermal efficiency %175(161)175170170175170195(170)Dust emission concerntration (mg/Nm3)<80<80<80<80<80<80<80Indentified thermal efficiency %79.279.5982.1782.379.5982.578.28 (steam boiler)76.75 (hot water boiler)Max part size for transportation (L×W×H) mm5370*2970*35506720*3400*35408800*3230*26009900*3400*35306720*3400*354010700*3550*34007570*3230*3540Max part weight for transporation cargo (t)3626.430.513626.44133.3Installed exterior size(L×W×H) mm8370*5330*38609000*5000*560011320*3600*540013000*4500*58009000*5000*560014000*4730*782011800*4250*5750
