SPQuery q = new SPQuery();
q.MeetingInstanceId = -1; //in case your document library is in meeting workspace, query items from all meetings
q.ViewAttributes = "Scope='RecursiveAll'"; //Query all folders (if this is not set, only current folder will be queryied)
q.Query = 



<Where>
      <And>
         <BeginsWith>
            <FieldRef Name='ContentTypeId' />
            <Value Type='Text'>0x0120</Value>
         </BeginsWith>
         <Eq>
            <FieldRef Name='Title' />
            <Value Type='Text'>Folder name</Value>
         </Eq>
      </And>
   </Where>

• The ContentTypeId part indicates that we want to query only folders
• The Title part is where you put in your folder name.

Then you execute query and get the id:

SPListItemCollection items = list.GetItems(q);
if (items.Count > 0)
  int folderId = items[0].ID

You can also enumerate list folders by using SPList.Folders property

I know this is an old thread but I tried the above example in a SP 2010 environment and it didn't work so I thought I'd add my working CAML. Instead of using the ContentTypeID field, I just used ContentType=Folder

<Where>
    <And>
        <Eq>
            <FieldRef Name='ContentType'/>
            <Value Type='Text'>Folder</Value>
        </Eq>
        <Eq>
            <FieldRef Name="Title"/>
            <Value Type='Text'>Folder Name</Value>
        </Eq>
    </And>
</Where>
