  One of the essential foundational industries for the growth of infrastructure and building is the cement industry; in 2021, the globe produced about 4.4 billion tons of cement. China is the world’s largest cement producer, with over 55% of the global capacity; India comes in second, with over 7% of the global capacity. Following the COVID-19 epidemic, there was an abrupt increase in demand for both urban and rural infrastructure expansions worldwide, primarily in developing nations. Long-term demand for cement products will result from initiatives like India’s Smart City project, which will push current cement plants to greatly upgrade their technological capabilities in order to optimize energy and cost. Among all industrial sectors, the cement industry is one of the ones that uses the most energy. Between 40% and 60% of industrial expenses are attributed to energy use. In addition, the cement sector accounts for 5% to 8% of global emissions of CO2 produced by humans. Today’s ce...

  In steel industries Blast furnaces have a key role in smelting iron ore together with fuel (coke) and flux (limestone) continuously supplied from the top of the furnace. Hot blast air with oxygen enrichment is blown into the lower section of the furnace through a series of pipes (tuyeres).  This results in chemical reactions while material falls downwards in the furnace.  Flue gas ( Blast furnace gas) a low calorie will exit from the top of the furnace which in turn is used in other low heating furnaces in other steel processes.  Blast furnace gas  typically consists of mainly N2(50-55%), CO (20-25%), CO2(16-18%) etc. It contains some moisture content and carbon particle dirt sticky in nature but cleanable. Leomi provides a  Leomi-586 Insertion Thermal Mass flowmeter  which works excellent in these demanding applications against existing Orifice Or Averaging Pitot tube-based DP type flow transmitters.

Cement Industry is one of the crucial core sectors for the development of construction and infrastructure with currently approx. 4.4 billion Tonnes of cement was produced in the world in the year 2021. The largest cement producer is China with more than 55% capacity and thereafter India accounts for the second largest product with around 7% of capacity. After the COVID-19 pandemic, there was a sudden rise in demand from rural and urban infrastructural developments across the world and mostly in undeveloped countries. Initiatives such as the Smart City project by India will see a long-term demand for cement products which will see huge technological upgradation of existing cement plants for cost and energy optimization. The cement industry is one of the most intensive energy consumers in the industrial sectors. Energy consumption represents 40% to 60% of production costs. Additionally, the cement industry contributes around 5% to 8% of all man-made CO2 emissions. Due to increasing deman...

Within this blog, we will discuss the different types of thermal mass flowmeter technologies. Thermal mass flowmeters operate on the principle where a heat source is applied to the inlet of the mass flow meter and is then transmitted from one part of the device to another, increasing in temperature (gain an amount of q) based on its thermal resistance. The change in temperature as a function of time causes a corresponding change in thermal conductance (change in convective heat transfer coefficient h). As fluid flows through a pipe it changes its speed due to frictional forces and if there is a thermocouple placed at various points within this pipe can determine how much varying thermal power dissipation occurs within that length by relating it back to a known conduit’s temperature gradient. Let us discuss the types of thermal mass flowmeters: 1. INSERTION THERMAL MASS FLOW METER if we have large pipes and don’t want to cut them, then maybe we can use an insertion thermal mass flow sen...
