You can try this code. 

 Query query =  myRef.child("Purchase_Request").orderByChild("Chimney_Purchase");

    query.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for (DataSnapshot snap: dataSnapshot.getChildren()) {
                if(snap.getKey().equals("your_key")) {
                    snap.getRef().removeValue();
                }
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
            Log.e(TAG, "onCancelled", databaseError.toException());
        }
    });
