Abstract

The application relates to the technical field of catalytic burners, and specifically discloses a catalytic coating and a double-layer microporous catalytic burner using the catalytic coating. The catalytic coating comprises a transition layer, a carrier layer and an active layer, and the transition layer is obtained by curing an adhesive, wherein the adhesive is made of raw materials comprising the following parts by mass: 40-60 parts of SB powder; Ce(NO 3 ) 3 ·6H 2 O 8‑12 parts; LaNO 3 ·H 2 O 8‑12 parts; HNO 3 20‑30 parts; 6‑10 parts of isobutyric acid; 60‑80 parts of deionized water. The burner body of the present application is added with adhesive, carrier and active components, so that the active components can be fixed to the surface of Fe-Cr-Al after being attached to the carrier, which relieves the catalyst load on the Fe-Cr-Al surface to a certain extent The problem that the amount is difficult to control, thereby improving the catalytic effect of the catalytic coating.

Description

technical field [0001] The application relates to the technical field of catalytic burners, more specifically, it relates to a catalytic coating and a double-layer microporous catalytic combustor applying the catalytic coating. Background technique [0002] A burner is a device that injects fuel and air in a certain way for mixed combustion, and is widely used in integrated stoves and other fields. [0003] The Chinese patent with the publication number CN107401742A discloses a double-layer microporous catalytic burner, which includes a main body microporous catalytic combustion plate matrix, and an auxiliary combustion plate matrix is ​​installed on the main body microporous catalytic combustion plate matrix. The mesh number of the matrix of the main body microporous catalytic combustion plate is higher than that of the matrix of the auxiliary combustion plate, the thickness of the matrix of the microporous catalytic combustion plate of the main body is greater than the thi...
