Using Steam & Getting It Back
Heat exchange, control valves, traps, condensate and flash recovery — the using half of the loop, and the recovering half.
- D1200°9 minHeating with steam: coils, jackets and exchangersIndirect heating done right — including the stall phenomenon that starves exchangers.
- D2200°8 minDirect steam injectionHeating by contact — where DSI wins and how to do it quietly.
- D3200°12 minHow to select a control valve for steamKv, critical pressure drop, characteristic and actuator — a worked selection, and what to do when control goes wrong.
- D4200°9 minDesuperheatersWhy processes want saturated steam, and how to take the superheat out.
- D5200°12 minSteam traps: the complete schoolTypes, selection by application, the trap station, and testing — the full working guide.
- D6200°10 minCondensate recoveryWater, heat and treatment — the three values in every kilogram of condensate, and how to bring it home.
- D7200°11 minFlash steam recoverySizing the vessel and finding the duty — turning flash from plume to product.
- D8200°9 minMetering steamOrifice, vortex and the installation rules — measuring the energy, not just the flow.
- D9200°8 minHot water from steamPHWG, calorifier or direct injection — three routes compared honestly.
- D10200°10 minSafety valvesThe last line of defence — function, terminology, sizing basics and installation rules.
- D11200°10 minVacuum steam heatingSteam below atmosphere: precise, gentle heating under 100 °C — what it buys, what the plumbing costs, and the vacuum-cooling sidebar.
- D12200°10 minClean and pure steamFour grades from boiler-house to injection-grade — filtered/culinary, clean and pure steam, and how to choose your rung honestly.
- D13300°11 minInside the shell-and-tube exchangerTEMA architectures, baffles, tubesheets and ratings — what the steam engineer must specify and check, without pretending to be the vessel designer.
