I lived within a few miles of the place and I remember when I was in the top class in the juniors, not sure what year that is now, I guess year 6. I was 11 so it would have been 1952 and a boy in our class fainted in class one day and from that it was found that he was hungry (unusual in our area and at our school even then) and he was sent to Styal. We understood it was to give him more fresh air. We all knew the school as more a convalescent home than a children's home/orphanage as amelinixon has posted.
He was only there a short time as I remember he went to the boy's grammar school the following year where all the other boys from our class went to, so he must have moved back home.
