することを目的とする。(c) Problems to be solved by the invention By the way, vaporizers are made of cast iron materials such as ordinary cast iron (gray cast iron) and spheroidal graphite cast iron, which have good workability. However, while the heat-resistant temperature of ordinary cast iron is 500°C or less, and the heat-resistant temperature of spheroidal graphite cast iron is 600°C or less,
Since the actual operating temperature of the heat recovery section of the vaporizer is 700 to 750°C, the heat recovery section of the vaporizer gradually deteriorates due to high-temperature oxidation and eventually falls apart, making it impossible to expect stable heat recovery. was there. Of course, actual fairness 1-13
As disclosed in Publication No. 214, if all or part of the heat recovery section is made of a super heat-resistant alloy, this problem can be solved, but the connection between the heat recovery section made of a super heat-resistant alloy and other parts is There was a concern that gaps would easily form in the joints, leading to poor heat transfer. This invention has been made in view of the above-mentioned facts, and aims to reduce deterioration of the heat recovery section of the vaporizer and enable stable heat recovery without impairing heat transfer performance. .
