Central Heating Boiler
Central heating means that the steam or hot water generated by the central heat source can supply the heat needed
for production, heating and living of a city (town) or part of the area through the pipe network. Central heating sources
include cogeneration power plants, central boiler houses, industrial and other waste heat, geothermal, nuclear, solar
energy, heat pumps, etc., or they can be multi-heat source combined heating systems composed of several heat sources.
At present, the heating boiler with hot water or more. They are mainly concentrated in hotels, residential areas and large
Types and Specifications of Boiler Suitable for Central Heating Boiler
Pressure :1.0 MPa
Fuel :Heavy oil, diesel, natural gas, lpg, etc.
Application : Hotel, school, building central heating, etc
Oil gas fired central heating system is to provide hot water or steam to the whole interior of a building from one heat
source to multiple rooms. Sitong Boiler produces large numbers of boilers that could used for central heating system.
Fuel :wood chips, bagasse, straw, olive bone, coconut shell,peanut shell, pellets, rice husk and other biomass fuels
Application : Central Heating, Textile plant, wood factory, rice mill, farm,paper mill, chemical plant,food plant, etc.
DZL Series chain grate wood fired fired boiler is drum boiler with both water tubes and fire tubes, the combustion equipment
is chaingrate, has the advantages of high efficiency, anti coking, and sufficient output, etc.
How to Select a Proper Boiler for Central Heating Boiler
1. Determine Boiler Medium
For heating enterprises that do not supply steam for industrial production but only provide heating for residents, the first choice is the hot water boiler as the heating boiler. Because the operation of hot water boiler is safer, more stable and more economical than regular boiler, meanwhile, the heating radius of hot water is about twice that of steam, and the maximum heating radius can reach 20 km.
2. Determine Boiler Capacity
General heating boilers are calculated according to area. For general residential, 1 ton of boiler heating area is 6000~8000 square meters. For the common workshop and other higher places and cold areas, heating area should be relatively reduced.
3. Determine Boiler Fuel
Boilers are divided into fuel oil gas boilers, coal-fired boilers, biomass boilers, electric boilers. The state strictly controls the coal-fired boilers. The gas-fired boiler should consider whether it is convenient to install the gas pipeline. If it is not convenient, oil-fired or electric boilers should be considered.
4. Boiler thermal efficiency
Boiler should has high efficiency. The boiler output, the number of sets and other performance can adapt to the demand of heat load change, in order to facilitate economic management. If the use of one boiler operating at full load can meet the demand for steam, it is not appropriate to use two boilers operating under lower load. However, from the perspective of safety production, it is necessary to consider whether a single boiler in operation can be started quickly in a short time due to failure, so as to meet heating requirements without affecting production.
5. Capacity and Model
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.
