Problems solved by technology

The existing solid additives have some disadvantages in the use of large boiler power plants and cement plants. During the use of solid additives, a forklift needs to be used to mix them evenly in the coal yard. If it is a large coal yard, this work is quite heavy and requires Increase the cost and it is easy to cause uneven mixing, inconvenient to use, uneven addition

Embodiment 1

[0018] Cerium nitrate 0.5%

[0019] Copper sulfate 5%

[0020] Potassium ferrate 2%

[0021] Sodium dodecylbenzenesulfonate 2%

[0022] Deionized water balance

[0023] Preparation method: Add the above-mentioned raw materials into the deionized water of the feeding amount in turn, and stir for 1 hour.

[0024] The usage amount of the liquid coal-saving sulfur-fixing agent is: liquid coal-saving sulfur-fixing agent: coal = 1:3000 (mass ratio), when used, it is diluted with 5 times the weight of water according to the degree of dryness and humidity of the coal, so as to spray evenly.

[0025] Through trial use, the invention reduces the combustion activation energy of coal, saves 5.2% of boiler coal, and fixes sulfur up to 48.6%.

Abstract

The invention provides a liquid coal-saving sulfur-fixing agent. Including cerium nitrate or holmium nitrate, copper sulfate or copper nitrate, potassium permanganate or potassium ferrate, sodium alkylbenzene sulfonate or polyvinylpyrrolidone, deionized water. The invention achieves the effects of coal saving, sulfur fixation, environmental protection and no negative impact on combustion equipment and the environment by reducing the activation energy. In addition, liquid additives overcome the shortcomings of solid additives, and are easy to operate and evenly sprayed.

Description

technical field [0001] The invention relates to a coal-saving additive, in particular to a liquid coal-saving sulfur-fixing agent. Background technique [0002] With the sustained and rapid economic development and the increasing population, coal consumption has increased significantly year by year. Coal combustion is the main way of coal utilization. my country's energy structure is dominated by coal. Every year, more than 2 billion tons of coal are used for direct combustion, causing serious pollution to the environment. To sum up, how to efficiently use resources and minimize pollution has become an important task before us. [0003] The current coal-saving sulfur fixatives are mainly divided into two types: liquid and solid. The existing solid additives have some disadvantages in the use of large boiler power plants and cement plants. During the use of solid additives, a forklift needs to be used to mix them evenly in the coal yard. If it is a large coal yard, this wor...
