This section carries the news of Arrow Energy Co., Ltd. in three categories, and applies the same editorial rule as the company's engineering resources: every claim carries a mechanism and a number with a unit. A commissioning story states the boiler capacity in t/h and, where the customer permits publication, the measured result in mg/Nm³ at stated O₂ — on the same nine-field basis as the project reference database. A technical note states its formula and its worked figures. An exhibition announcement states the event, place and stand.
NEWS CATEGORIES — WHAT EACH ITEM MUST STATE
| Category | Typical item | Must state |
| Project milestones | Award, erection complete, performance test passed | Capacity (t/h), scope; results in mg/Nm³ @ stated O₂ where permitted |
| Technical notes | Short engineering pieces on ESP, Electrocyclone and boiler practice | Formula, worked numbers, basis |
| Exhibitions | Industry events — Fenasucro (Brazil) and PHILSUTECH (Philippines) are typical of the calendar | Event, dates, location, stand |
Why publish technical notes instead of press releases?
Because the readers of this site are plant and procurement engineers, and an engineer gets nothing from a press release. A note that shows, with numbers, why an economizer retrofit returns 3.1–4.0 percentage points — or how to back-calculate migration velocity from a quotation — is useful whether or not the reader ever buys anything. That usefulness is the point.
Two things this section deliberately does not do. It does not announce project awards before contracts are signed, and it does not attach performance figures to a project until they have been measured — commissioning results appear here only after the performance test, on the stated basis the contract defined. Exhibition attendance is announced per event as each calendar is confirmed; no standing schedule is claimed. Items stay short: a milestone is a paragraph and its numbers, a technical note rarely exceeds the length of one worked calculation, and anything deeper belongs in the permanent engineering calculators rather than in a dated post.
