Embodiment Construction

[0009] In order to better understand and implement the technical solutions of the present invention, some embodiments of the present invention are provided here. These examples are for better explaining the technical solutions of the present invention, and do not constitute any form of limitation to the present invention.

[0010] A method for improving waste heat power generation in cement production, comprising the following methods:

[0011] (a) A certain amount of coal gangue is added to the cement batching to increase the calorific value of the batching;

[0012] (b) When the width of the impeller of the clinker cooling fan remains unchanged, the diameter is increased by 5-10%, and the motor of the cooling fan remains unchanged;

[0013] (c) Add a water preheating pipeline at the exhaust gas outlet of the preheater. The water preheating pipeline is connected to the water inlet of the power generation boiler. The coal gangue content in the cement ingredients is 2-5%, and ...

Abstract

The invention discloses a method for improving cement production waste heat power generation capacity and belongs to the technical field of cement production waste heat power generation. The method comprises the following steps that (a) a certain amount of gangue is added to cement raw materials, and the heating capacity of the cement raw materials is improved; (b) the diameter of an impeller of a clinker cooling draught fan is increased by 5% to 10% under the condition that the width is not changed, and a motor of the cooling draught fan is not changed; (c) a water preheating pipeline is additionally arranged at a waste gas outlet of a preheater, and the water preheating pipeline is communicated with a water feeding channel of a power generating boiler. By the adoption of the method, the cement production waste heat power generation capacity can be increased by 8% to 10%, and the comprehensive benefits of cement production can be effectively increased.

Description

technical field [0001] The invention relates to a method for increasing waste heat power generation, in particular to a method for improving waste heat power generation in cement production, and belongs to the technical field of waste heat power generation in cement production. Background technique [0002] China is a big country in cement production and consumption. Cement production is a high-energy-consuming industry. In particular, there is still a certain gap between China's production technology and the world's advanced level. The energy consumption of cement production is the main component of the cost of cement production enterprises. In order to reduce cement production Energy consumption, industry technicians and management personnel use various methods to optimize the production process, and comprehensively utilize the waste heat of cement production. The waste heat power generation of cement production is one of the important measures. There is a lot of waste heat...
