[Equest-users] Boiler Fuel Type / Hot Water Pipe Properties

[John Aulbach via Equest-users]

Sir:
If you are familiar with the DETAIL-EDIT mode, place your project in that Mode (after making a copy of it to stay in Wizard mode) - by all means give it another name to avoid confusion.
On the Horizontal Tab that says UTILITIES and ECONOMICS, you can then go to the tree hierarchy on the left side of the page. Go to subfolder FUEL-METER and click on. The main screen now displays FUEL-METER attributes. Now if you click FUel Meter Type, Coal will appear. Make sure the Btu/unit is what you expect from your Coal, as i understand there are several types in use.
Hope this helps.

 I don't personally know the answer to your question on the fuel source coal vs. natural gas.Regarding the 2nd question on simulation of piping pressure and thermal losses; these modelling software programs do not model these energy losses. They don't "care" where your central utility plant is physically located in relation to your load. They make the assumption that you have properly sized pipelines, insulation etc. EQuest is only attempting to estimate the fuel consumption of meeting the building's heating and cooling load, not assess the pipe sizing and insulation condition.David Berty, P.E.

Hi everyone :)
I am a new user and modelling a district heating system. Probably my questions are easy, but i couldnt solve the problems.
1- I define boiler but the fuel type must be coal. However, Equest doesnt let me get the results for coal. It simulates as natural gas. Even i create new fuel meter for coal and select it on boil properties. How can i get the results for coal? (Maybe it is related to pic1. But there is no other choice except Natural Gas )
      2- As i mentioned before, this is a district heating system and there are 6 residential villas. Combined Heat Power Plant supplies the hot water and it is located very far away. I wanna see the effect of pipe lenght, dimension and insulataion material of the hot water pipes. So,  how can i enter the pipes and their properties?

Sincerely.
