Product Introduction
Steam boiler desuperheater is a device used to regulate the temperature of superheated steam. 1. The surface type desuperheater is a tubular heat exchanger, which takes the boiler water supply or pot water as the cooling water. The cooling water flows through the tube and the steam flows horizontally through the outer space of the tube. 2. Mixed type (water spray type) desupreheater is to spray water directly into the superheated steam to achieve the purpose of cooling. It has the advantages of simple structure, large temperature regulating capacity and small inertia, sensitivity and easy automation, and is the most widely used temperature regulating equipment.
Product Advantage
Steam boiler desuperheater: Spray atomized cooling water directly into the temperature-regulating water vapor and make it evaporate into water vapor and mix well with the temperature-regulating water vapor to reduce the temperature of the temperature-regulating water vapor device. According to the structure of the cooling water injected into the temperature-regulating water vapor, it can be divided into Venturi type, vortex type and porous nozzle type. The principle is that part of the saturated water vapor is cooled into condensed water by water supply and sprayed into the desuperheater to regulate the temperature. Water injection depends on the pressure difference between the condenser and the desuperheater, without the need for special desuperheater water pump. The characteristics of water jet desupreheater are simple structure, large temperature range (up to 50℃--65' C), sensitive temperature regulation, easy to achieve automation, therefore, widely used in boilers.
Product Structure
In order to control the temperature of superheated steam, a desuperheater is installed at the outlet of the superheater. The structure of the conventional desuperheater is to insert a desuperheater pipe in the steam pipe, and the desuperheater pipe is opened with a number of small holes. The desuperheater ejected from the small holes and mixed with the superheated steam in the pipe to achieve the cooling effect.This structure of the desuperheater in the work of the mixing uniformity of desuperheater and superheated steam is not very good, the temperature of superheated steam is difficult to control, especially when the number of superheated steam changes, the regulating performance of desuperheater can not meet the needs of the change, resulting in superheated steam temperature beyond the range.
