Embodiment 1

[0028] The invention provides a kind of cement for high temperature resistant gas-fired boiler, wherein, it is composed of the following raw materials in parts by weight:

[0029] 5 parts of natural gypsum; 40 parts of mineral powder; 9 parts of fly ash; 6 parts of silica fume; and 42 parts of clinker.

Embodiment 2

[0031] The invention provides a kind of cement for high temperature resistant gas-fired boiler, wherein, it is composed of the following raw materials in parts by weight:

[0032] 8 parts of natural gypsum; 46 parts of mineral powder; 12 parts of fly ash; 8 parts of silica fume; and 52 parts of clinker.

Embodiment 3

[0034] The invention provides a kind of cement for high temperature resistant gas-fired boiler, wherein, it is composed of the following raw materials in parts by weight:

[0035] 7 parts of natural gypsum; 42 parts of mineral powder; 10 parts of fly ash; 8 parts of silica fume; and 55 parts of clinker.

[0036] Wherein, the clinker fineness is S=350m 2 / Kg, the fineness of the cement powder for the high temperature resistant gas boiler is 380-450m2 / Kg.

[0037] Clinker, gypsum, mineral powder, fly ash, silica fume, etc. are the main raw materials for the production of cement for high-temperature resistant gas-fired boilers. Cement grinding is a key step in the production of cement for boiler furnaces. Open-circuit high-fine grinding The grinding system grinds clinker and mixed materials through a homogenizer and then mixes with slag powder to prepare marine Portland cement powder.

[0038] Among them, the clinker fineness remains unchanged (S=350m 2 / Kg) and only the incre...

Abstract

The invention discloses cement for a high-temperature-resistant gas boiler. The cement is prepared from, by weight, 5-8 parts of natural gypsum, 38-46 parts of mineral powder, 8-12 parts of fly ash, 5-8 parts of silica fume and 33-55 parts of clinker. The cement for the high-temperature-resistant gas boiler has high durability, high construction property and high heat resistance, and can be mainly applied to preparing a heat-resistant high-temperature-resistant boiler hearth.

Description

technical field [0001] The invention relates to a cement, in particular to a cement for a high-temperature-resistant gas-fired boiler suitable for a boiler furnace. Background technique [0002] Due to the convection of high-temperature flue gas, the cement used to make boiler furnaces is easy to corrode the boiler furnaces made of cement. [0003] The existing boiler cement not only has low heat resistance, but also has relatively low erosion ability, so it is urgent to invent a boiler cement with high temperature resistance and corrosion resistance. Contents of the invention [0004] The purpose of the present invention is to provide a high-temperature-resistant cement for gas-fired boilers to solve the problem of low heat resistance of cement for boiler furnaces in the prior art. [0005] In order to achieve the above object, the present invention provides a kind of high temperature resistant gas-fired boiler cement, wherein, it is composed of the following raw materia...
