Specific configuration selection of breeding hot air stove

0010010 nbsp; 0010010 nbsp; 0010010 nbsp; 0010010 nbsp; The specific matters that need to be paid attention to in the specific configuration selection of breeding hot air furnace are as follows:

There are many types of gas hot blast stoves on the market today, and there are many manufacturers. When selecting specifically, we suggest that the safety, operability and adaptability of the hot blast stove should be considered under the premise of considering the thermal efficiency.

(1) Safety Safety is mainly due to the fact that the gas itself is flammable. During the selection process, pay attention to whether the hot blast stove is equipped with fire protection, overheat protection, leakage protection alarm, overpressure limit and other safety protection settings To ensure the safety of users' personal and property.

(2) Operability is to check the degree of automatic control of the product, whether the safety measures can be started automatically, whether accurate safety control can be achieved, the degree of intelligence of the operation switch temperature controller on the fuselage, and Indicators such as controllability of the unit and monitoring of operating parameters.

(3) Adaptability Adaptability refers to the selection of a suitable breeding hot air stove according to the size of the shed area. The heating area of ​​an indirect heating type gas hot air furnace is usually {{1}} ~ 500 m 2 , the hot air furnace with a power of about 20 kw, propane The consumption is usually between 0. 6 ~ 1. 3 kg / h, which can be used to heat {{1}} m 2 ; When the power reaches about 50 kw, the fuel consumption (take propane as an example) of the hot blast stove is usually 2 ~ 4 kg / h, and the heating area can reach 500 m 2 ; In practical applications, the hot blast stove should be reasonably selected according to the size of the shed. When a single hot blast stove is installed in the shed, it is recommended to place the hot blast stove in the middle of the shed, the exhaust pipe and the outlet The air outlet is exhausted in the opposite direction, and an induced draft fan is installed at the outdoor air outlet, so that the heat generated by the hot air furnace can be used to a greater extent, and the thermal efficiency value is increased. It should be noted that the length of the exhaust pipe should not be too long (less than 3 0 m is appropriate). If the exhaust pipe is too long, the exhaust gas is blocked, and the exhaust gas is easily discharged internally, which affects the normal use of the hot blast stove and poses a great potential safety hazard.

Other considerations

Due to the limitation of the heating method of the breeding hot air stove, the internal ground temperature of the greenhouse is usually lower than the upper part. For the purpose of local surface heating or water heating, it can be used in conjunction with the geothermal line and electric heating rods. The heating effect has better gain effect. The liquefied gas or propane purchased in ordinary small greenhouses are usually canned, and the temperature of the tank should be maintained during use. The normal use of the gas in the liquefied gas tank requires a vaporization process, and vaporization requires heat absorption. If the temperature of the tank is too low, the gas in the tank is not fully vaporized and the pressure is insufficient, which affects the normal use of gas. In actual operation, the tank can be seated in a bucket filled with hot water, or the liquefied gas tank can be placed in a safe location slightly closer to the hot blast stove to heat the tank using the heat generated by the hot blast stove.
