Heating in greenhouse is one of the oldest horticultural revolution. Generally, hot water boiler is widely used as the central heating system. A central boiler is used to heat water between about 120F and 180F. With the technology developed, hot air stove is used more and more widely, which could instead of the hot water boiler for central heating, more over, it could used for crops drying.
Types and Specifications of Boiler Suitable for Green House
Fuel: heavy oil, diesel, natural gas, LPG, city gas, coke gas, etc.
WNS series hot water boiler is smoke gas three pass and wet back structure, and by equipped with condenser , the boiler achieves high thermal efficiency (98%) . It equipped with PLC automatic control cabinet and safety interlock device, operate safely and conveniently. This is fire tube boiler, low water quality requirement, the failure rate is lower than 0.1.
Fuel: coal, wood, bagasse, straw, rice husk,other biomass fuels.
DZL coal/biomass fired chain grate boiler realizes almost zero pollution with special dust collector solution. Sitong Boiler takes Takes several measures to avoid coking, bulging, and tube plate cracking, has the advantages of compact structure, high thermal efficiency, sufficient output, and low cost.
Fuel: Coal/wood pellet/biomass fuel
Brief Intro: ZLRF series coal/biomass hot air stove is a vertical type energy saving heating equipment with simple structure, the heating principle is heat transfer, and the heat medium is hot air. Temperature rise up quickly, low heat loss, and low cost.
Price of Green House Boiler
The price of green house boilers is based on the capacity and accessories. Generally, the accessories of boilers include burner/grate, electric controller, steam header, water softener, BFW pump, platform ladder, and chimney, etc. If you would like to use the specific devices (brand, materials, quantity, etc.) or the additional equipment (air preheater, economizer, condenser, etc.), the prices are quite different. So, if you would like to get the exact price, please inquire for the details.
How to Select a Proper Boiler for Green House
1. Determine the capacity of the boiler. The boiler capacity should based on the Heating Load Curve or Heat Balance Diagram, and includes the heat loss in pipelines, self-used heat of boiler room, available used waste heat. While, usually, it is difficult to get the Heating Load Curve, the heating load could get based on the max thermal consumption per hour within production/heating/domestic, and then determine by using the coefficient.
2. Determine the boiler heating parameters, including pressure, temperature, etc.
3. Determine the boiler efficiency. In order to benefit for economic management, the boilers should have high thermal efficiency, and the boiler output, quantity and other performances have to adapt to the change of heat loading.
4. It is better to select the boilers with same capacity or combustion equipment. If different, the max limitation is two models, to decrease the problems of equipment layout and management.
