<p>The present invention disclosed a tube cap on the top of the slag-drip tube in a boiler, which is set on the capping of the slag-drip tube; the tube cap on the top of the slag-drip tube includes a supporting unit, a connected component and a tube cap. The tube cap mentioned above comprises an integral forming columnar tube cap unit and a curved coping, and there is at least one trepanning on the tube cap. The supporting unit consists of at least two stents, one end of each stent is connected with the tube wall on the top of the slag-drip tube, and the other end is connected with the tube cap through the connected component. This invention has provided a tube cap on the top of the slag-drip tube in a boiler, which is able to slow down the falling velocity of the slag so that it can avoid the wearing of the slag-drip tube and itself by the slag, as a result, it can avoid the impediment and blockage of the slag-drip tube by the larger particles of the slag.</p> |
