Reviews of Emerson's Integrated Differential Pressure Flowmeter Helping Photovoltaic Glass Industry

In order to achieve emission reduction and carbon reduction in response to global climate change, China has introduced a series of policy measures to continue to promote the rapid development of the photovoltaic industry, and China's photovoltaic industry has entered a stage of further acceleration. Benefiting from the rapid development of the photovoltaic industry, as an essential material for photovoltaic modules, the demand for photovoltaic glass has been increasing, which has greatly stimulated the enthusiasm of photovoltaic glass enterprises for production. In the first half of this year, many manufacturers have expanded their production capacity, including Follett, Xinyi Solar, Kibing Group, and CSG Group, all of which have released production expansion plans.

Photovoltaic glass Industry challenges

Photovoltaic glass is a kind of special glass that can use solar radiation to generate electricity by laminating into solar cells, and has related current extraction devices and cables. Photovoltaic glass products are processed from the original ultra-white patterned glass. In the original production line, melting, forming and annealing are the core links, which directly affect the quality and production rate of the product, and the operation of the kiln will also affect the thermal efficiency of the product. How to precisely control the combustion of the furnace, reduce fuel consumption, and improve the combustion efficiency of the furnace has always been a challenge faced by the glass manufacturing industry.

Application Challenge 1:

Measurement of natural gas flow

The most common fuel in glass melting furnaces is natural gas, whose cost accounts for about 40% of the cost of glass production; it is a multi-component mixed gas, and changes in components will cause changes in parameters such as relative density and compression factor. In addition, during the flow of natural gas, its temperature and pressure are also constantly changing. Therefore, it is a great application challenge to accurately measure the natural gas flow.

In this application, Emerson's integrated multi-parameter balanced flowmeter 3051SFC solution has been widely recognized. The outstanding advantages are reflected in the following points:

The 3051SFC integrated multi-parameter balance flowmeter adopts Emerson's multi-parameter flow transmitter 3051SMV, which can use the database natural gas data model, real-time dynamic temperature and pressure full compensation to ensure high-precision flow measurement.

The 3051SFC integrated multi-parameter balance flowmeter integrates the multi-parameter flow transmitter 3051SMV with the balance orifice plate.

Only the straight pipe section of 2 times the pipe diameter upstream and downstream is required, and the selection requirements for on-site installation points are very low.

It adopts the installation method of flange clamping and has its own centering design, so the on-site installation is very simple and convenient.

The flowmeter has good performance and can provide a 15-year stability guarantee.

Application Challenge 2:

Flow measurement of combustion air

The size of the pipeline of the combustion-supporting air in the furnace is relatively large, but the pipeline pressure is relatively small. Therefore, to ensure a stable and reliable measurement of the combustion-supporting air flow, it is necessary to minimize the pressure loss of the combustion-supporting air.

Emerson pressure flow measuring equipment

Emerson's integrated Annu and Abba flowmeter 3051SFA also has many mature applications in the flow measurement of combustion air. Its outstanding performance is as follows:

The measurement method of Annubar flowmeter 3051SFA inserted into the pipeline is not limited by the size and shape of the pipeline. It is especially suitable for fluid measurement in large pipelines, which simplifies the installation process and greatly reduces engineering construction and labor costs.

The flow element adopts a T-slot design structure, which has the lowest pressure loss in the same type of products, the highest signal sampling rate and signal-to-noise ratio, ensuring stable measurement performance in the full range.

The integrated assembly of the flowmeter, the overall pressure test before leaving the factory, minimizes the potential leakage point, ensures the safety of on-site production, and the installation is simpler.

Emerson's integrated differential pressure flowmeter series has a lot of achievements in the glass industry, and has also been recognized by the majority of industry insiders. Through stable, reliable and accurate measurement of combustion air flow and natural gas flow in furnaces, it can help users maximize combustion efficiency and reduce energy consumption, thereby helping enterprises reduce operating costs and reduce flue gas emissions.
