The fuel cost of 10 tph electric boiler: 7,100 kilowatt-hour is multiplied by the local industrial electricity unit price which is nearly 1 RMB, so we can get 1 RMB/kWh and the fuel cost is about 7,100 RMB per hour.
It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.
Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
Gas-fired boiler products used in different industries will be different. With the increasingly stringent environmental protection policies issued by the state in recent years, gas-fired boilers are widely used in all walks of life. The quotation of different configurations of gas-fired boiler varies greatly, and the quotation of 3-ton gas-fired boiler does not have a fixed amount, because the quotation of 3-ton gas-fired boiler system is composed of boiler body price and auxiliary equipment pri...
Most petroleum products can be used as fuel, and boiler oil is a kind of refined oil, which is widely used in power plants and industrial boilers. Boiler oil is mainly made of petroleum cracking residue oil and straight-run residue oil, which is characterized by high viscosity and high content of non-hydrocarbon compounds, gum and asphaltene.
The formula of boiler oil mainly includes the following indicators: viscosity of the boiler oil, sulphur content, density, flash point, water content and ...
Gas-fired boiler is a kind of thermal equipment that uses the thermal energy released by fuel combustion or other thermal energy to heat the medium to the rated temperature. With the strict environmental protection, gas-fired boilers are widely used in power generation, heating, factory processing and so on. Boiler thermal power refers to the continuous heat production per unit time of hot water boiler at rated parameters, rated flow, designed fuel and guaranteed efficiency. So how to convert th...
Combustion system: The combustion system of coal-fired thermal oil heater includes base, grate, furnace, etc. The combustion system of oil/gas heat-conducting oil boiler includes furnace, burner, ignition device, etc.
Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
Control system: complete with boiler control box.
Air-smoke system: refers to the system composed of flue gas and air generated by combustion, mainly including induced draft fans...
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
The primary air fan of the boiler consists of motor, impeller, casing, air inlet box, current collector, base, regulating control system, etc.
The working process of the primary air fan: Take the medium-speed coal mill and direct-fired pulverizing system as examples, the atmosphere enters the primary air fan and is divided into two paths after being boosted by the primary air fan. One path of the atmosphere enters the primary airpipe in front of the coal mill. The other path enters the air preh...
