Equipment design for gas and air heat exchangers

As the title suggests, the company plans to design a device for exchanging heat between gas and air; let’s call it a gas-air heat exchanger for now. The specific parameters are: gas inlet temperature of 850°C, outlet temperature of 650°C, and gas flow rate of 10,000 standard cubic meters/h. The air inlet temperature is 15°C, the outlet temperature is 300°C, and the air flow rate is 6000 standard cubic meters/h. Because I have never done this kind of design before, I have no idea at all. I would like to ask the following question: ① How should the heat exchange area be calculated, and what is the specific calculation process? ； ②, the steel material to be used for the equipment, approximate weight ； ③It would be better to have similar drawings, structural diagrams, exterior views, and detailed plans. You can pay to buy the blueprints; the price is negotiable. I earnestly ask all experts to share their insights. Thank you again. Urgent. .
The key is that there’s no design pressure; if the pressure isn’t high, it should be similar to the design of a economizer. You can refer to this link for your calculations: http://wenku.baidu.com/link?url=awQ5BktCQMtAMozoSivDXB9jz2IJK8ntcvTLasGm4HlWU1v3g2Nim6bnkS2uaQe5fi70abMGSgHpL_eiAa64ZM195cwg-o8ABkIE8SV6igO
I haven’t been to the forum for a long time; thank you, wgonline, for your reply.
