To show the Featured Image of a particular post, Please use following code.

<?php if (has_post_thumbnail( $post->ID ) ): ?>
   <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ),                                                         
       'single-post-thumbnail' ); ?>
    <div id="custom-bg" style="background-image: url('<?php echo $image[0]; ?>')">
    </div>
<?php endif; ?>
