Method for determining peat as received basis lower heating value

Abstract

The invention discloses a method for determining the peat as received basis lower heating value. The method includes the steps that by means of coal analysis, the total moisture of peat, the dry basis ash content of the peat and dry ash-free basis volatile parameters of the peat are acquired; the superposed cumulative sum of products of the total moisture of peat, the dry basis ash content of the peat and the dry ash-free basis volatile parameters of the peat and corresponding coefficients respectively is calculated; a peat heating value constant and the superposed cumulative sum are subtracted, and the peat as received basis heating value is calculated, wherein the larger the peat as received basis lower heating value is, the better the peat quality is. The peat as received basis lower heating value can be accurately calculated, the inspection time of the peat can be shortened, and finally the purpose of improving power production efficiency is achieved.

Description

technical field [0001] The invention belongs to the field of thermal power generation, and in particular relates to a method for determining the low calorific value of peat receiving base. Background technique [0002] Coal resources are my country's largest energy source and the basic energy material required for industrial development. my country's coal resources are very rich, accounting for about 70% of my country's total energy. [0003] In the domestic coal trade, the calorific value on the received basis is the most commonly used calorific value index, and its size directly affects the level of the trade settlement price. The greater the calorific value on the received basis of peat, the better the peat quality . According to the national standard, the process of measuring the calorific value of peat is quite cumbersome, time-consuming and labor-intensive. It is not only necessary to measure the calorific value of coal, but also to carry out a series of measurements...

Problems solved by technology

According to the national standard, the process of measuring the calorific value of peat is quite cumbersome, time-consuming and labor-intensive. It is not only necessary to measure the calorific value of coal, but also to carry out a series of measurements on the coal's total moisture, total sulfur, hydrogen, moisture and cartridge calorific value. Determination experiments involve experimental equipment such as balances, ovens, muffle furnaces, sulfur analyzers, and elemental analyzers. The project determination experiments are particularly complicated and require three steps: equipment stabilization, instrument calibration, and experimental operations. At least 2 to 3 days
