ZG Boiler company can supplier two types coal fired hot water boiler for heating greenhouse,one type is chain grate coal fired hot water boiler and another is coal fired CFB hot water boiler.Mostly people will choose coal fired chain grate hot water boiler for their greenhouse heating.
Heating is used to provide optimal temperatures for crop growth and for management of the humidity in the greenhouse. Heating may be needed throughout the year, not just in winter. Heat should ideally be applied as low as possible in the greenhouse (with the exception of "grow pipes") and distributing heat evenly is essential for optimal crop production.
There are essentially two methods of heating - hot air and hot water. Hydronic heating refers to the use of a boiler to heat water which is then piped through the greenhouse. The pipes, located around the walls of the structure and/or between plant rows, radiate heat. The major costs are in the boiler and piping. A centralised hydronic heating system is generally a more efficient form of heating in greenhouses greater than 1000m2 and especially where there are several separate greenhouses. When hot water heating is used, the boilers may be situated away from the greenhouse. This flexibility provides the opportunity to locate potentially noisy boilers away from farm boundaries to minimise disturbance to neighbours.
Heated air can also be used to maintain temperatures in a greenhouse. Hot air may be directly generated in the greenhouse or the internal air can be warmed through heat exchange with an external heat source. Where combustion occurs at the source of the heat, such as in a gas fired heater, locating the heater outside the greenhouse and using a heat exchange pad to warm the internal air is recommended. This is because the combustion process can result in ethylene production and also water vapour. Ethylene can cause leaf drop and premature ripening of fruit. Increased moisture levels in the air may result in excessive humidity and condensation problems.
Gas remains the primary source of energy for greenhouse heating in Australia. Oil, diesel and coal are also used. Natural gas is lower cost and clean burning. It does not require on-farm storage tanks and is typically low maintenance. Unfortunately, natural gas is not available in all areas. Bottled gas (LPG) is similar to natural gas but more expensive. Costs can be volatile and storage tanks are needed.
Oil and diesel are more expensive than natural gas and because these fuels do not burn as cleanly, more boiler maintenance is needed. On-farm storage is also required.
Coal is relatively low cost if it is locally available. It is more polluting than other fuel sources. Large storage areas are needed on farm as well as loading equipment. As coal does not burn as cleanly, significant boiler maintenance is needed.
