Abstract
Sulfur-fixing coal saving agent in a kind of Boiler Furnace.The present invention replaces common lime stone using nano-calcium carbonate in stove, so as to greatly reduce dosage.Not only desulfurized effect is better than common lime stone, and reduce due to using large quantities of lime stone and caused by thermal losses, saved coal consumption, reached the double effectses of sulfur-immobilizing coal-saving.
Description
The invention belongs to coal combustion and sulfur fixation coal-saving additive, for boiler furnace sulfur fixation and the additive economized on coal.
Boiler fired coal desulfurization is divided into three kinds of methods：By coal washing desulfurization before combustion, although coal washing can reduce sulfur content, very
Difficulty reaches discharge standard；Although flue gas desulfurization desulfurized effect is preferable, investment is larger, and desulphurization cost is also higher；Add lime
Stone desulfuration in furnace can reach preferable effect, while again without big investment.
Although it is simplest method to add lime stone desulfuration in furnace, the efficiency comparison of its desulfurization is low.Due to lime
Stone is graininess, and specific surface area is still smaller after decomposition, after CaO and SO2 or the SO3 reaction on surface, it is prevented that in particle
CaO further participate in reaction.Therefore, more lime stone need to be used in desulfuration in furnace, typically in Kg more than 100, in addition it is useful
Arrive 200Kg's.So, substantial amounts of heat energy is just consumed, hence it is evident that reduce steam coal rates.
In view of true above, it is an object of the invention to provide a kind of effect that can reach solid sulphur, and can greatly reduce by
In the sulfur-fixing coal saving agent for adding large quantities of lime stone and consumption of calorie.The present invention is to use nano-calcium carbonate desulfuration in furnace.Nano-sized carbon
Sour calcium has big surface area, can reach 40-50 square metres/g, and this can greatly reduce the dosage of nano-calcium carbonate, both reach
The effect of solid sulphur has reached the effect economized on coal again, therefore is called sulfur-fixing coal saving agent.
The present invention is realized by the following method.
Embodiment 1)
8 parts of nano-calcium carbonate is taken, 6 parts of nano magnesia, adds in 86 parts of water, by high-speed shearing machine, suspension is made,
Obtain finished product.
Embodiment 2)
10 parts of nano-calcium carbonate is taken, 4 parts of nano magnesia, adds in 86 parts of water, by high-speed shearing machine, suspension is made
Liquid, obtain finished product.
This product is uniformly sprayed on coal using sprayer unit during use, fountain height 0.1-0.3%.
