A hot blast stove system for heating in a seedling-growing greenhouse

Abstract

The invention discloses an air heating furnace system for supplying heat to a seedling greenhouse, which comprises a combustion chamber, a heat exchanger, a heat exchange cover and a hot air pipe, wherein the combustion chamber comprises a combustion chamber body, a coal feed port, an ash cleaning port, a plurality of radiating fins and a vertical flue; the heat exchanger comprises a first header, a second header, a plurality of finned pipes, an ash cleaning door, a smoke exhaust fan and two clapboards; the heat exchange cover comprises a heat exchange cover shell, the ash cleaning port of the heat exchange cover, the coal feed port of the heat exchange cover, the ash cleaning door of the heat exchange cover, a horizontal flue port, a pair of draught fans, a main air port and a hot air pipe joint; the coal feed port is arranged above the ash cleaning port and used for importing coal and air into the combustion chamber body; the ash cleaning port is arranged at the lower part of a front side of the combustion chamber and used for discharging combusted coal ash from the combustion chamber; the vertical flue, the first header, the finned pipes and the smoke exhaust fan are used for discharging the smoke to the outside after the coal is burned. The system disclosed by the invention is capable of effectively decreasing the coal consumption, producing hot air at proper temperature and reasonably and uniformly conveying the heat so as to guarantee quick and uniform growth of seedlings.

Description

technical field [0001] The invention belongs to the technical field of seedling raising facilities, and more specifically relates to a hot blast stove system for heating a seedling raising greenhouse. Background technique [0002] According to the coverage method, the existing seedling raising technology is divided into three categories: greenhouse seedling raising, small arched shed seedling raising and land seedling raising, and according to the seedling raising nutrition body, it is divided into four types: seedling raising tray seedling raising, nutrient pot seedling raising, nutrient pool seedling raising and nutrient bag seedling raising kind. Modern agriculture aims at intensification, conservation and industrialized production. Therefore, in terms of seedling cultivation, modern greenhouse seedling cultivation has become the mainstream trend. Compared with small arched shed seedling cultivation and land seedling cultivation, it has many advantages. The most important...
