BOILER PRESENTATION ON INDUSTRY SITE.pptx

It is important topic. That can saving industry cost

1. INTEGRATION OF WASTE HEAT FROM INCINERATOR- 1 WITH 25 TPH BOILER INCLUDING FLUSH DRYER UTILIZATION Motto- Fuel Saving Scope- Study of heat generation, Losses & utilization Feasibility & implementation plan Investment & ROI Presented by- Sridhar Ch. Maity & Soumalya Roy Mentor- Mayank Gupta sir & Himanshu Tyagi sir

2. "UTILIZING WASTE HEAT FROM THE INCINERATOR IN THE BOILER ENHANCES EFFICIENCY AND LEADS TO SIGNIFICANT FUEL SAVINGS."

3. DESIGN DATA BOILER Boiler Name- Sitson Boiler (AFBC) Steam pressure- 48 kg/ Steam Temp- 425±5 °c Boiler Capacity- 25 TPH Fuel- Rice husk/ Saw dust Design ἡ- 82% Actual ἡ- 81%   INCINERATOR Design Capacity- 10 ton/ Day Saw Dust Drying Capacity- 100 MT/ Day Waste water evaporation- 15 KL/ Day Rice husk dust cal. Value- 3200 KL/ Day Waste cal. Value- 4000 KL/ KG STUDY OF HEAT GENERATION

4. POTENTIAL OF IDENTIFICATION PARAMETER DESIGEN Total heat generate by the incinerator (A) (10000*4000) =400 lakh. kcal/day Heat required for evaporation of effluent water evaporation (B) (15000*540) =81 Lakh. kcal/day Heat requirement for saw dust drying process (C) (20000*540) =108 lakh. kcal/day Residual heat in a system (D=A-B+C) =211 lakh. kcal/day

5. The average price of biomass INR 5.50 /kg Daily cost saving INR 35 K Annually saving cost of fuel INR 123 Lakh Residual heat in a system {A-(B+C)} 211 lakh. kcal/day (based on design data) At boiler ἡ 82% LOSSES CAN BE UTILIZED: We can get, From calculation @48 Kg/cm2 The mass of the steam will be generate 31969 kg/day From Boiler effiency formula , In calculation method The saving will be of biomass 6432 kg/day

6. Remains excess heat {A-(B+C)}= 2.11 Cr. kcal/day 667.78 is the subtraction value of feed water and steam enthalpy from steam table Steam generate potentiality : 21100000 / 667.78 at pr. 48 kg/ = 31 ton steam /day   Incinerator having total 11 chamber Water evaporation at 9 and 10 chamber approx. 650℃ Saw dust drying at 11 chamber 160℃

7. FEASIBILITY Our 25 TPH boiler system has completely surrounded by water panels. The current design is difficult to install ducting in boiler system One solution we have , we install the ducting line fix in the road side ,this side of boiler water panel should be changed, and all boiler system pipelines should be modified We also need another ID fan or modify our id fan because our ID fan is running in its full rpm. For modifying a boiler's pressure line in India, we must follow the procedures and codes specified in the Indian Boiler Regulations (IBR), 1950. A modification is considered a "structural alteration, addition, or renewal" and requires mandatory prior approval from the Chief Inspector of Boilers.

8. IMPLEMENTATION PLAN Ducting system planned along the roadside to utilize available space. Duct installation on the right side of the boiler, near the control room, is not possible due to the presence of concrete columns and the bucket elevator in that area. Duct installation in front of the boiler system is not feasible due to the presence of the rice husk yard, bag filter, and air preheater located on the front side of the boiler.

9. LIMITATION The boiler system will become complicated After installing the new system the surrounding space will be congested the steam of effluent water present in the flue gas which will corrode the boiler tubes and affect in the boiler system the bag filter will be effected The boiler will have to be maintenance short duration The bag filter will have to be changed in short time period The system will install more time consume This system modification may take time 15 days of breakdown. Complicity of boiler design

10. INVESTMENT Water Panel redesigning cost approx. 10 to 15 lakhs . New Water Panel material cost approx. 30 to 40 lakhs Crane handling cost approx. 1.5 lakhs per day. Installations cost 5 to7 lakhs Shutdown requirement 10 to 15 days Incinerator modification approx. 30 Lakh Ducting Cost approx . 20 lakh Isolation dampers approx . 10 Lakh Miscellaneous cost approx . 50 lakh

11. One year cost of fuel saving INR 123 Lakhs its our saving The modification costing approx. 200 lakh. RETURN OF INVESTMENT IN 1 YEAR 6 MONTH YEARLY SAVING
