Problems solved by technology

[0003] Chinese patents, such as 90106347.9, 98107116 (00113884.7), have disclosed some coal-burning combustion-supporting agents, but they generally have the disadvantages of large consumption, short combustion-supporting time, and high cost.
In terms of the preparation method of coal-fired combustion aids, the common feature is simply mixing the active materials with ball milling, which greatly reduces the effectiveness and combustion-supporting time of the combustion aids.

Embodiment 1

[0029] Active material selection: Potassium permanganate: 2 kg

[0030] Sodium carbonate: 4 kg

[0031] Sodium chloride: 15 kg

[0032] Ferric nitrate: 9 kg

[0033] Carrier Selection: Kaolin 70kg

[0034] The preparation steps are as follows:

[0035] 1) Prepare 2 kg of potassium permanganate as a 25% aqueous solution, soak 5 kg of kaolin in the aqueous solution for 12 hours, and bake at 80°C for 30 minutes to obtain product A.

[0036] 2) 4 kg of sodium carbonate and 15 kg of sodium chloride were prepared into a 15% aqueous solution, 45 kg of kaolin was soaked in the solution for 12 hours, and baked at 100° C. for 30 minutes to obtain product B.

[0037] 3) Prepare 9 kg of ferric nitrate into a 40%-60% solution, soak 20 kg of kaolin in the solution for 24 hours, and bake at 120°C for 1 hour to obtain product C. Mix A, B, and C products and ball mill them to obtain finished products.

Embodiment 2

[0039] Active material selection:

[0040] Potassium permanganate: 2 kg

[0041] Sodium chlorate: 2 kg

[0042] Sodium chloride: 6 kg

[0043] Cobaltous nitrate: 4 kg

[0044] Triethylhydrosilane: 6% 6 kg

[0045] Carrier selection: zeolite molecular sieve 80 kg

[0046] The production steps are basically the same as in Example 1, except that the zeolite molecular sieve is soaked in a saturated solution of cobaltous nitrate for 24 hours, baked at 120° C. for 1 hour, and then soaked in an acetone solution of triethylhydrosilane for 24 hours. Bake at 100°C for 2 hours. Then it is mixed and ball-milled with zeolite molecular sieve assembled with other active substances to obtain the finished product.

[0047] Refer to Table 1 for Examples 3-8.

Abstract

The fuel coal intensifier consists of active matter and carrier. By means of multi-element nano mesopore assembling technology, active matter is assembled into nano holes in carrier to obtain the high-activity long-acting fuel coal intensifier. The carrier is zeolite molecular sieve, pearlite, Kaolin, bentonite or their mixture; and the active matter consists of oxidant, catalyst, puffing agent, sulphur fixing agent and activating agent and includes the compound of K, Na, Mn, Co, La, Zn and Ce as well as ethyl hydrogen silane. The intensifier can raise heat efficiency obviously, save coal, fix sulphur and reduce dust and its cost is low.

Description

Technical field: [0001] The invention relates to an industrial additive, in particular to a novel coal-burning enhancer, and also relates to a preparation method of the novel coal-fired enhancer. Background technique: [0002] Coal combustion plays a pivotal role in the development of the national economy. At present, the development and utilization of energy in various countries in the world has mentioned a new level of understanding. The issue of energy crisis also occupies a very important position in our country's strategic planning. However, in production and application, the utilization rate of coal is generally low, resulting in serious energy waste. Improving the efficiency of coal use can not only directly produce huge economic benefits, but also has great significance in environmental protection, and plays an irreplaceable role in promoting and guaranteeing the country's long-term development strategy. [0003] Chinese patents, such as 90106347.9, 98107116 (0011...
