Unfortunately you misunderstood me.

What I want to do is to override drawers export to exclude some
predefined drawers. Let's say: LOGBOOK and CLOCKTABLE.

Then I want to attach these drawers to headline(!)
This is why I want to add a piece of code to return drawer in org-html-headline.

Yes. I want to hard-code these drawers and ignore them in default export.

Anyway thing is that I want to export drawer with specific name while
I'm in org-html-headline function.

(defun org-html-headline (headline contents info)
  "Transcode a HEADLINE element from Org to HTML.
CONTENTS holds the contents of the headline.  INFO is a plist
holding contextual information."
  ;; Empty contents?
  (setq contents (or contents ""))
  (let* ((numberedp (org-export-numbered-headline-p headline info))
         (level (org-export-get-relative-level headline info))

         And here I wan't to add:

         (clocktable (and (plist-get info :with-drawers)
                  (let* ((drawers (org-element-map headline 'drawer 'identity 
info nil 'headline)))
                    (mapconcat (lambda (d)
                                 (when (string= (org-element-property 
:drawer-name d) "CLOCKTABLE")
                                   (org-export-data-with-backend d 'html info)))
                               drawers ""))))


In this way I could attach HTML code with CLOCKTABLE drawer to headline.
Unfortunately as I mentioned before I don't know how to achieve this
without recursion. My code returns all CLOCKTABLE drawers in child
tasks.

org-element-map has optional argument 'no-recursion' but I don't know
how to set it up properly.
