Method for safe operation of steam commercial 250 bhp condensing boilers prices steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, if you accidentally quenching phenomenon occurs, the device will automatically interlock burner saver appear. It must be promptly cut off the natural gas pipeline to start the furnace purification. Replacement of the residual gas in the furnace and closed. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.

Oil and gas commercial 250 bhp condensing boilers prices in overseas markets

Biomass boilers are very popular in overseas markets due to their energy saving and environmental protection characteristics, but oil and gas boilers are selling well in overseas markets due to their ease of use, high efficiency, and environmental protection.

Phase out coal-fired commercial 250 bhp condensing boilers prices, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.

The phase-out of coal-fired boiler from the following three points.

First, the coal-fired boilers carry out a comprehensive investigation work.

Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.

Second, carry out the phase-out coal-fired boilers.

Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.

Third, strongly promote the boiler-depth treatment.

Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.

Biomass fired commercial 250 bhp condensing boilers price fuel characteristics

Biomass fuel has the following main characteristics compared to coal:

1. Low sulfur content. Biomass fuels are mostly less than 0.2% sulphur, and there is no need to install a gas desulfurization device when burning, which reduces costs and is environmentally friendly.

2. Most of the carbon in the biomass fuel combines with hydrogen to form a low-molecular hydrocarbon. After a certain temperature, it thermally decomposes and folds out the volatiles. Therefore, biomass fuel is easily ignited,

3. The density is small. The density of biomass fuel is obviously lower than that of coal, and the texture is relatively loose, especially crop straw, which is bulky.

4. Less carbon. The highest carbon content in biomass fuels is only about 50%, which is equivalent to the carbon content of lignite with less generation.

5. Straw biomass contains a large amount of alkali metal elements (mainly potassium and sodium). In the combustion process of biomass, the main performance is that the adhesion of ash is strong, and slagging and clogging are likely to occur in the furnace. Ash accumulates on the heated surface of the tail.
