WebOverview. This calculator allows users to derive NO 2 from NO x wherever NO x is predicted by modelling emissions from roads. The calculator can also be used to calculate the road component of NO x from roadside NO 2 diffusion tube measurements. Local authorities are advised to use the latest version of the tool for all future work that is ... Webemissions also need to be corrected for the fuel NO. x. from ammonia. Fuel NO. x. is assumed 0.5 wt percent of inlet NH. 3 4. 2. The high-B tu waste streams referred to streams have a heating value greater than 1,000 Btu/scf. 3. Net heat release assumes a basis of 1 scf. 4. NH. 3. to fuel NO. x. conversion is subject to case-by-case review.
