  1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktor Lange; [2023]
    Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

  3. 2. Optimal dead space in axial-type expander

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Karman; [2022]
    Keywords : Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Abstract : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. READ MORE

  4. 3. Designing of two load bearing surfaces in a modern high-speed steam engine

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Anders Söderbäck; [2022]
    Keywords : Ranotor Modern high-speed steam engine mechanical engineering KISSsoft Bevel gears; Ranotor Ångmotor KISSsoft Maskinteknik;

    Abstract : The topic of this thesis is the designing of two load bearing surfaces in a modern high-speed steam expander. One of the surfaces is a synchronizing gear structure and the other a conical surface. The goal besides the design is to calculate the contact pressure these surfaces experience during operation.

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

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johan Samuelsson; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE
