Fuel Gas Hot Thermal Oil Boiler Biomass Thermal Oil Heater Three Return Cylindrical Structure

600000 kcal 700kw fuel gas hot thermal oil boiler organic heat carrier furnace biomass thermal oil heater

Structure Description:

1, Structural features:

The YY(Q)W-700Y(Q) type organic heat carrier furnace is a horizontal three-return cylindrical structure, which adopts the central combustion mode of the imported burner. The heated surface is made of 20 (GB3087-2008) seamless steel pipe of φ51×3 mm. The import and export headers are made of 20 (GB3087-2008) and φ108×4.5mm seamless steel tubes. Calculate the total pressure drop of the furnace tube by hydrodynamics to 0.13MPa

According to the design specification parameters, we calculate the flow rate of the selected circulating oil pump to 50m3/h. According to this, the medium flow rate of the radiation heating surface can be calculated to be 2.62m, which is greater than 2m/s, and the medium flow velocity of the convective heating surface is 2.62m, which is greater than 1.5. m/s, and the circulation resistance in the furnace is much less than the pressure of the circulating pump on the medium, which is in full compliance with the relevant provisions of TSG G0001-2012 "Boiler Safety Technical Supervision Regulations" and GB/T17410-2008 "Organic Heat Carrier Furnace".

2, Process requirements:

According to the company's existing process equipment conditions, the manufacturing process of this type of heat carrier furnace can be met, subject to the following requirements:

1. The entire manufacturing process complies with the relevant regulations in TSG G0001-2012 “Boiler Safety Technical Supervision Regulations” and GB/T17410-2008 “Organic Heat Carrier Furnace”.

2. All coils must be welded by argon arc welding and non-destructive testing after welding. The detection ratio should be in accordance with Table 4-2 of TSG G0001-2012 “Boiler Safety Technical Supervision Regulations”.

3. After the single-pass coil is finished, it should be tested by water pressure. The test pressure is 2.0MPa and the pressure holding time is 10-20s. After the test pressure is passed, the assembly process can be entered.

4. After the assembly of the body is completed, the hydraulic pressure test shall be carried out. The test pressure is 1.5 MPa and the dwell time is 20 min. After the test pressure is passed, the air is blown and sealed with compressed air to prevent impurities from entering.

5. The installation and acceptance of the boiler shall comply with the relevant provisions of GB50273-2009 “Code for Construction and Acceptance of Boiler Installation Engineering”.

6. Auxiliary equipment

7. Automatic control
