Research and application of negative pressure control on ground floor and waste heat utilization of power plant boiler houses in severe cold zone
The boiler house of power plants in severe cold zone is a super tall space building with internal heat sources,and the negative pressure on the ground floor is high in winter,making it difficult to ensure the heating effect.In this paper,the solution to supply outside air from the upper part of the boiler house is proposed.This scheme can increase the indoor pressure,reduce the negative pressure and cold air penetration on the ground floor,and transfer heat downward.Because the heat dissipation of the boiler house equipment is much greater than the heating load,in the case of suitable air supply,the heating system can be shut down without affecting the heating effect of the ground floor,which not only ensures that the equipment on the ground floor is not frozen,but also saves the heating energy,and also improves the working environment of the upper part of the boiler house.
