Abstract

The design for a boiler room process design in Hohhot Economic Development Zone, construction area of 380,000 square meters, the heating method is taken directly from the 95/70 ℃ hot water heating boiler. In this article , the principles of this heat plant and the design data this has been explained In detail. This paper gives a reasonable basis for equipment selection and the type of major equipment.According to the architectural design energy saving requirements, calculate the maximum thermal load of 17.85 MW. This design choose three set CDZL7.0-1.0/95/70-Ptype boiler. A single boiler is rated at 7.0 MW, working pressure of 1.0 MPa.

The boiler room of raw water hardness and oxygen content do not meet the requirements of the boiler feed water, to soften and the need for oxygen treatment.According to supply water flow, the design uses two LNN-800 / 8 model of the regeneration of fixed bed countercurrent ion exchange of sodium and choose one CJYZS-10 type analytical deaerator. Two sodium ion exchange, in turn used to run.

Based on the hydraulic calculation to determine the size of the pipeline section and water pump and fan model.

Keywords: coal-boiler; heating with hot water; Water treatment ; The wind system
