Natural Gas fired hot water boiler Hot Selling

Note the boiler operating at low load range of the boiler load change is normal: coal-fired boilers typically 70% -100% of rated evaporation; oil furnace is 60% -100% of rated evaporation. Below this range is the low-load operation. The main problem is the low-load operation, poor combustion stability, we must prevent the fire and explosion at the furnace, natural circulation boiler must also consider the safety of the water cycle. Thus, when low load operation, the boiler attention to the following aspects: 1, should be as low-load burning high volatile coal. When low volatile coal, during unstable combustion, combustion should be put into the ignition oil gun, in order to prevent possible fire. 2, input at low load the burner should be more uniform, the number of burners should not be too small, which is good for both combustion stability and prevent individual parts of the water circulation is not normal. 3, the speed should be slow changes in the load, and adjust the air volume. Note that maintain a steady wind pressure, which should be the primary air volume is too large. Burner input and deactivation operation should be slow. 4, oil-fired boiler during low load operation, since it is difficult to ensure the combustion quality of oil, should be taken to prevent droplets caused by the re-ignition of unburnt flue tail. 5, low load operation, to minimize the use of desuperheating water (mixing desuperheater), but it should not be heated Save the door shut. 6, low load operation, the exhaust gas temperature is low, the possibility of low temperature corrosion is increased. Therefore, they should put warm or hot air recirculation.

There are two types can designed for gas oil fired boiler.One type is gas oil fired fire tube boiler and another is gas oil fired water tube boiler.Gas oil fired water tube boiler is a packaged boiler with double drums and D-type layout. It has lots of advantages such as sufficient burning, no pollution in the emission, convenient operation, easy installation etc.

Currently, Yancheng City, Jiangsu Province, has issued the latest "Battle of Yancheng win the blue sky plan", in full swing atmospheric environmental governance. Details are as follows.

First, to promote non-power industry emissions of nitrogen oxides depth and steel industry to implement ultra-low emissions transformation. Achieve before the end of June 2020 discharge standards garbage incineration industry, gas-fired units are encouraged to implement advanced nitrogen removal, implementation of coal-fired units plume of white vapor recovery off the project.

Second, the implementation of total coal consumption control. Accelerate the "Yancheng reduce total coal consumption special action plan", strictly implement the same amount of coal consumption reduction alternative requirements, increase bulk coal remediation efforts for non-electric Yajian coal industry, and gradually increase the proportion of coal. New coal coal project implementation reduction instead. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, the power sector coal consumption accounts for the proportion of total coal consumption to increase more than 65%. Continue to promote alternative energy coal and oil, electricity consumption by 2020 (calculated as the supply of standard coal) accounted for about 55% of the total social energy consumption.

The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. Strict control of new coal-fired units installed capacity, the new electricity in the area rely mainly on non-fossil energy generation and transmission to meet outside.

Third, carry out comprehensive improvement of coal-fired boilers. Before the end of 2019, 35 tons of steam / hr and coal-fired boilers or eliminated all clean energy alternative embodiment, suitable remediation in accordance with the principle of the electric power, gas and other appropriate gas is to encourage the use of solar energy, and biomass energy; promote clean coal use, promoting clean and efficient coal-fired boiler, steam 65 t / h coal-fired boilers and more energy-efficient and ultra-low emissions completed transformation; low-nitrogen gas boiler is substantially complete transformation; urban area biomass boilers embodiment ultra low emission transformation; rest boilers with all the special emission limit requirements.
