  1. 1. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Johan Samuelsson; [2022]
    Nyckelord :Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Sammanfattning : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. LÄS MER

  3. 2. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Gautam Rajeev; Dinesh Thirunavukkarasu; [2021]
    Nyckelord :Steam engine; rotational valve; actuator mechanism; sealing; Ångmotor; rotationsventil; ställdon; tätning;

    Sammanfattning : A novel compact steam engine design could be used to replace current combustion engines in the rapidly changing world of renewable energy. Especially with the increased research into alternative fuels such as hydrogen fuel cells and methane, which would vastly improve the efficiency of a steam engine. LÄS MER
