High-efficiency energy-saving emission-reducing combustion improver for fire coal and application method thereof

Abstract

The invention relates to a combustion improver, especially to a high-efficiency energy-saving emission-reducing combustion improver for fire coal and an application method thereof, belonging to the field of combustion additives for coal. The combustion improver comprises the following components by weight: 20 to 40 parts of potassium nitrate, 20 to 40 parts of potassium permanganate, 10 to 30 parts of manganese dioxide, 5 to 15 parts of zinc chloride, 5 to 15 parts of barium nitrate and 20 to 40 parts of sodium chloride. Compared with the prior art, the invention has the following advantages and beneficial effects: through changing a traditional formula and utilizing the characteristics of substances like potassium nitrate, potassium permanganate, manganese dioxide, zinc chloride, barium nitrate, sodium chloride and zinc oxide, ignition temperature of coal is decreased, the oxidation speed of coal is increased, burning-out time of coal is shortened, combustion conditions are improved, the burning-out rate of coal is accelerated, ash content and carbon residue are reduced, combustion efficiency is improved, the caloric power of combustion is enhanced, emission of harmful gases like carbon dioxide and nitrogen oxide is lowered, and the purposes of energy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of coal combustion additives, in particular to a combustion-supporting agent for high-efficiency coal-burning, energy-saving and emission-reducing combustion-supporting agent and a use method thereof. Background technique [0002] Coal is the main energy source in my country, accounting for nearly 70% of the total primary energy consumption in my country. In 2013, the output of raw coal was 3.68 billion tons. Dry-process cement kilns, power plant boilers, and steel kilns are major coal consumers, which inevitably lead to the emission of harmful substances such as carbon dioxide and nitrogen oxides. There is a huge pressure on energy conservation and emission reduction. my country is also a big coal consumer. Due to backward combustion technology, incomplete combustion, and low combustion efficiency, low-quality coal with low energy levels is not used or is rarely used and is wasted. The problem of energy waste is seri...
