Steam, saturated, 11 bar(a)

What it is

Per 1 t of saturated steam at 11 bar(a) from a natural-gas fired boiler, make-up water at 15 degC (no condensate return). Gate-to-gate: boiler, deaerator and feed pump. Combustion emissions (NOx, CO, CH4, N2O, PM) are EPA AP-42 Section 1.4 factors for a small uncontrolled boiler, on an energy basis.

A file with this activity alone is not available: each file above is the whole database, and the line under it says how to find this activity there.

import bw2data as bd
from cheme_as_code_lci import install

bd.projects.set_current("my-project")   # holds your licensed background + biosphere3
install("cheme-as-code-atlas-preview-c3ab348.xlsx", background="ecoinvent-3.11-cutoff", location="DE")
activity = bd.get_activity(("cheme-as-code-atlas-preview-c3ab348", "utility-steam-ng-boiler:steam-mp-11bara-natural-gas-boiler:product:steam"))

While any exchange of the database has no mapping, install() writes nothing and only lists the unlinked exchanges. So the last line finds no activity until the gaps are mapped: the download section gives the ways to use the database now.
